DeleteFile fails with 'The system cannot open the file'

In my installer (Basic MSI project) I have a file to be installed under following location - C:\Program Files\Common Files\AppFolder\AppFolder2\17\drivers\test.dll 

I wanted this file to exist only during the installer process.  Post install I want to delete the file.  So I have added a CustomAction to delete the file however I keep getting  "The system cannot open the file". 

My customAction function:

function DeleteDLLFile(hMSI)
STRING szCommonFilesDir, szMBSWVersionDir;
NUMBER nSize,nSize2,nResult;
STRING szFilePath;
// Get the installed path location
MsiGetProperty(hMSI, "TSSCOMMONFILESFOLDER", szCommonFilesDir, nSize);
SprintfMsiLog("In DeleteDLLFile - TSSCOMMONFILESFOLDER - " + szCommonFilesDir);
MsiGetProperty(hMSI, "MBSWVersion", szMBSWVersionDir, nSize2);
SprintfMsiLog("In DeleteDLLFile - MBSWVersion - " + szMBSWVersionDir);
szFilePath = szCommonFilesDir ^ "AppFolder2" ^ szMBSWVersionDir ^ "drivers" ^ "test.dll";

SprintfMsiLog("In DeleteDLLFile - Before path changes '%s'", szFilePath);
// replace backslashes with double backslashes
StrReplace (szFilePath, "\\" , "\\\\", 0);
SprintfMsiLog("In DeleteDLLFile - After path changes '%s'", szFilePath);

SprintfMsiLog("In DeleteDLLFile - Before calling DeleteFile '%s'", szFilePath);
nResult = DeleteFile ("'" + szFilePath + "'");
if (nResult < 0) then
SprintfMsiLog ("Failed to delete '%s' reason '%s'", ERRORFILENAME, FormatMessage(nResult));
SprintfMsiLog ("File '%s' was deleted.", szFilePath);

SprintfMsiLog("In DeleteDLLFile - Finished calling DeleteFile() with file path '%s'", szFilePath);
