6 Network Administrator Information

Note to network administrators on installing MPLAB IDE v7.30 and later in a secure environment:

MPLAB_X_YY.MST file is a Windows installer transform file, located in the full zipped installation of MPLAB IDE vX.YY. This file can be used by domain administrators with Microsoft Active Directory and group policies to assign the application for software deployment in a security environment (local machines do not have admin rights). Microsoft Active Directory can be used to assign the application to local workstations. It has not been tested for "assigning/publishing to users." If this is a first time install, you may need to install the isscript10.msi first. Apply the transform file to the MPLAB_X_YY.MSI installation file in the group policy object (GPO). All of the files in the MPLAB IDE vX.YY full download zip must be located on a shared network directory.

7 Multiple Installations of MPLAB IDE v7.xx and later

Multiple versions of MPLAB IDE v7.xx may be INSTALLED on the same PC.

NOTE: You still may not RUN multiple versions of MPLAB IDE at the same time, i.e., only one version will be registered on the PC.

If necessary, you may switch between installed MPLAB IDE versions (i.e., change which one is registered) by following these steps:

To switch between v7.00 through v7.10:

· Open a Command Prompt window (Start>Programs>Accessories>Command Prompt).

· Find the installation directory of the v7.xx that you want to run.

· In the MPLAB IDE Common directory, execute mpswitch.exe -l to determine the installed v7.xx versions of MPLAB IDE on your system. The version marked with an asterisk is the active version.

· Execute mpswitch.exe <version>, where <version> is the v7.xx to which you wish to switch. For example, to switch from MPLAB IDE 7.01 to MPLAB IDE 7.00:
C:> mpswitch.exe 7.00

To switch between v7.11 and v7.20 (and later versions):

· Double-click on the icon of the version you wish to run.

· Configuration>Settings, Other tab - Added "Automatically reload files that were modified outside the IDE". Check to prevent the display of a warning box when rebuilding and using instrumented trace with the MPLAB REAL ICE in-circuit emulator.

· MPLAB IDE will automatically convert your older (v7.42 or older) workspaces to v7.43.
Note: You will not be able to go back once you have converted (i.e., MPLAB IDE v7.42 and older will no longer be able to open the converted workspace, though they can open the project.)

· Work-around: Open the project instead of the workspace, and then save the workspace. Note: If you plan to go back, make a copy of your old workspace file so you can retrieve it.

· PICkit 2 users should not upgrade from MPLAB IDE v7.42 to v7.43. They should wait till v7.50.

9 Known Problems

The following is a list of known problems. For information on common problems, error messages and limitations, please see Troubleshooting in the online help file for MPLAB IDE (hlpMPLABIDE.chm).

9.1 Launch Issues

The splash screen flashes, but MPLAB IDE will not launch

Applies to MPLAB IDE versions 7.01 and 7.10.

When you try to start MPLAB IDE, the splash screen flashes by, but the application does not launch. This only occurs on machines with non-administrator (user-only) privileges.

Note: Administrator rights are required to install, but should not be required to run.

The workaround is to modify the target path on the MPLAB IDE shortcut and append the option -noswitch:

mplab.exe -noswitch

You can reach the target path by selecting the MPLAB IDE icon on the desktop, right-clicking properties, and then selecting the shortcut tab.

MPLAB IDE used to work, but now it will not launch

Items to check are:

· Did you recently install another version of MPLAB IDE? Please see section 7 for information on switching between versions of MPLAB IDE.

· Did you recently install other software? If so, it may have overwritten a system DLL in such a way that other applications cannot use it. Consult the software documentation and the Windows OS documentation to determine how to repair or reinstall the correct system DLL.

· Did you recently edit your PC registry? MPLAB IDE uses the registry to find related files. Try reinstalling MPLAB IDE.

· Do you have virus protection software on your machine? Try other programs on your PC to see if they are functioning correctly. If not, you may have a virus.

9.2 Operating System Issues

· "File not found" error on Windows NT systems, usually from an import or project manager build. This is a Windows NT v4.0 issue, not an MPLAB IDE issue. Update Windows NT v4.0 with service pack or set registry flag HK_CU\Network\DeferFlags = 1. For more information, see: http://support.microsoft.com/default.aspx?scid=kb;en-us;169138

· On Windows 98/ME, for every open Editor window, a message box entitled "File Time warning" appears with the content, "The parameter is incorrect". This happens after a build or after minimizing and restoring the application's main window.

Fix: Close MPLAB IDE and run the batch file located, by default, at:

C:\Program Files\Microchip\MPLAB IDE\Core\Editor\Register Old Editor 9x.bat

Restart MPLAB IDE and select Help>About MPLAB IDE. Verify that SVEditor.dll, and not SVEditor4.dll, is registered. If the batch file fails, you may need to update your PATH to include the path to regsvr32.exe (wherever it is installed on your system.)

· Once the program is installed and you attempt to run it, you might receive an error stating that a dll file failed to register. This is caused when Windows does not allow the MPLAB IDE installation to register the file for some reason. You will need to select Start>Programs>Microchip>MPLAB IDE vx.xx>Setup MPLAB Tools and run Repair to install and register the file.

9.3 General Issues

· "Access Denied" message when trying to open a workspace. Make sure the workspace and related files have not been set to read-only, i.e., right-click on a file, select "Properties", and check that "Read-only" is NOT selected.

· If you use MPASM assembler to assemble a single file (i.e., you do not use the assembler with MPLINK object linker), you will get a COD file which has a 62 character length restriction for file and path names. To solve this problem either (1) Use MPLINK linker with MPASM assembler to create a COFF file, which has no character length restriction, or (2) Shorten your file name or move your file into a directory closer to the root directory (shorten the path name), and try assembling your file or project again.

· Some language (build) tools may have problems if you use spaces, illegal characters or long file names for the file or project name. Consult the language tool documentation for details.

· If your language tools do not work correctly after installing this version of MPLAB IDE, go to our website or third party website to get the latest version of your language tool. If you have purchased the tool, contact your sales rep for an upgrade.

· When using a System Display Font Size of Large Fonts (125% normal), and selecting an Italic font, some characters may display truncated on the top-right border of the source editor.

· Several of the Editor fonts are Symbol based and are not suitable for use with the Editor. The Symbol fonts are included in the selection list to allow users to select the Terminal font.

· The Editor allows files to be saved in UNICODE format on these UNICODE enabled operating systems: Windows NT 4.0 SP6a Workstations (NOT Servers), Windows 2000 SP2, Windows XP. Those files stored in UNICODE format will NOT compile with the present language tools, and you can not use them to debug.

· MPLAB ICD 2 existing projects must be updated to operate correctly because of GUI interface changes. With the project open:

o Select Project>Build Options>Project. When the dialog opens, click OK. (This is necessary to save new Build Options in the project. Previously there had been a checkbox option for "Link for ICD2" on the MPLAB LINK30 tab. This is now gone and has been replaced by a drop-down option on the Project Manager toolbar.)

o On the Project Manager toolbar, select "Debug" from the Build Configurations drop-down list.

o Rebuild the project. (Use Build All - Make does not work with this configuration yet.)

9.4 System Service Requests (SSRs)

SSR 21029: While most Win NT users have been able to use the MPLAB IDE, a limited number of Win NT users have reported being unable to run MPLAB IDE. Microchip Development Tools has determined that one cause of this problem is that Windows Desktop Update is not installed on the user's PC. See the Microsoft web site for more information about the Windows Desktop Update. Another cause of the problem for Win NT users may be due to a registration problem; the work-around: run register.bat in the dll subdirectory of the MPLAB IDE installation directory.

SSR 23550: While in Animate mode, if you select File>Exit, MPLAB IDE will crash.

SSR 24945: MPLAB IDE fails to save the individual .asm file options in a project; it reverts to the project 'Build Options'.

SSR 25806: [COFF] dsPIC disassembly listing shows address rather than Wreg number.

SSR 26249: Build Options' Include Path does not recognize multiple paths if a space is placed after the semicolon.

SSR 26635: Project Wizard: Save Workspace As dialog defaults to Core folder instead of project folder.

SSR 27730: MPLAB C18 with full optimizations and procedural abstraction set to 2 selecting optimization "debug" still have pa=2 on the command line

SSR 27761: For dual processor PC's, attempting to program with MPLAB ICD 2 after having done an Add file in Subversion results in an IDE application error.

SSR 27778: Subversion: Selecting the Help button from the SVN Commit Everything dialog has no effect.

SSR 28053: Trying to select a document from the MPLAB IDE Document Select dialog opens the browser but there is no content. Work around is to have a browser window open prior to using the MPLAB IDE Document Select dialog.

SSR 28374: Stimulus controller starts behaving erratically after executing about 922000 instruction cycles when multiple SCL processes are running concurrently.

SSR 28391: Logic Analyzer is currently only cycle based.

SSR 28758: For AN851, HPC Explorer/PIC18F8722 behaves inconsistently. Programming and reading of device are successful sometimes and unsuccessful other times.

SSR 29051: For AN851, some configuration bit locations (code protect 0x300008 for example) cannot be programmed.

SSR 29085: After an uninstall of MPLAB IDE v7.42, MPLAB IDE v7.41 does not run correctly. Workaround: Use Repair on v7.41.

SSR 29288: No warning that MPLAB IDE converting older workspaces to v7.43.
