Thanks for your help. Looks like I forgot to reset nvSize after the MsiGetProperty call and before the ExpandEnvironmentStringsA call. Bila ... View more

What are you setting MAX_PATH to be? Why can't nvSize be hardcoded inside the function to say nvSize=256 since we don't expect the path to be longer than 256 characters? Thanks, Bila ... View more

After some more investigation it seems that this issue occurs whenever I call MsiGetProperty (hMSI, "CACHE_ROOT", svCacheRoot, nvSize); The svCacheRoot is set by the user in a silent install batch script. If I remove the above call and hardcode svCacheRoot inside the script (ie. svCacheRoot="%USERPROFILE%" ) the call returns the correctly expanded string. I could reproduce this even when I changed the way I call the function to: prototype INT kernel32.ExpandEnvironmentStringsA(BYVAL STRING, BYREF STRING, INT); export prototype ExFn_CreateCacheDir(HWND); function ExFn_CreateCacheDir(hMSI) STRING svCacheRoot, svCacheRootExpanded, svUILevel; NUMBER nvSize; INT intRetval; STRING svEnvVar; STRING svInstallDir; STRING svCantSaveFilesHere; begin nvSize = 256; MsiGetProperty (hMSI, "CACHE_ROOT", svCacheRoot, nvSize); intRetval = ExpandEnvironmentStringsA( svCacheRoot, svCacheRootExpanded, nvSize); MessageBox(svCacheRootExpanded,0); SprintfBox (INFORMATION, "return value ", "retval: %d", intRetval); MessageBox ("path: '" + svCacheRoot + "'", SEVERE); MessageBox ("expanded path: " + svCacheRootExpanded, SEVERE); Thanks, Bila ...

Thanks Bineesh. This command produced a more verbose log that indicated the user needs to be Administrator in order to run the uninstallation. It's a bit strange since the user does have "Administrator" permissions and was the same user who installed the application. Uninstallation was successful once I ran the uninstall batch file "as Administrator". ... View more
