.NET Forum / .NET Framework / Compact Framework / August 2007Installation not working on WM6?
Some (but not all) users are indicating that my application does not install successfully when they upgrade to WM6 (no problems on same device with WM5). The application folder gets created in the /Program Files path, but no files exist inside the folder. Sounds like the installation is rolling back before it finishes, however, there are no error messages. I'm using NETCF2. Any ideas? Have you tested it on the WM6 emulator to see if it fails there?

Did some more testing. Turns out that if i remove the reference to "SETUP.DLL" in the installation package, it installs just fine. I'm using that standard setup.cpp project to create a setup.dll that makes some registry edits during installation. Is there a reason why WM6 doesn't allow this? Is your setup.dll signed?

Is this a new requirement in WM6? Additional info: Using File Explorer through ActiveSync, i can literally see the files getting installed while the CAB file is installing. Then, on the last step, all the files get removed including the application folder. And the CAB file states "installation completed successfully" After much research, i discovered a single method in Setup.cpp which caused the installation to roll back: SHGetSpecialFolderPath(...) as used here: (from Setup.cpp) /////////////////////////////////////////////////////////// //PURPOSE : HANDLES TASKS DONE AT END OF INSTALLATION /////////////////////////////////////////////////////////// codeINSTALL_EXIT Install_Exit( HWND hwndparent,LPCTSTR pszinstalldir, WORD cfaileddirs,WORD cfailedfiles,WORD cfailedregkeys, WORD cfailedregvals, WORD cfailedshortcuts) { TCHAR _path [100]; // Gets Program Files path SHGetSpecialFolderPath(NULL, _path, CSIDL_PROGRAM_FILES, 0); <--------- This line is the culprit This all works just fine in WM5 or prior. But no-go in WM6. If i comment out that single line, the installation will not rollback in WM6. Solution: Change TCHAR _path [100]; to TCHAR _path[MAX_PATH]; Then this line works: SHGetSpecialFolderPath(NULL, _path, CSIDL_PROGRAM_FILES, 0); That is, the installation does not roll back on WM6. Update on this -- I tried installing to the WM6 Professional Emulator and it did not install either. No folder or anything, but the system said installation was successful. ??
