Just in case someone else is trying to do something similar, i have managed to get it to work function CopyUserManual(hMSI) STRING dataPath, error, sourcePath; NUMBER nvType, nvSize, nResult, nBufferSize; begin RegDBSetDefaultRoot(HKEY_LOCAL_MACHINE); RegDBGetKeyValueEx("SOFTWARE\\EuroAvionics\\EasyTask", "ETGSDataPath", nvType, dataPath, nvSize); if (StrLengthChars(dataPath) > 0) then //Do Nothing else RegDBGetKeyValueEx("SOFTWARE\\Wow6432Node\\EuroAvionics\\EasyTask", "ETGSDataPath", nvType, dataPath, nvSize); endif; nBufferSize = MAX_PATH; MsiGetProperty(ISMSI_HANDLE, "SETUPEXEDIR", sourcePath, nBufferSize); nResult = CopyFile(sourcePath ^ USER_MANUAL_NAME, dataPath ^ USER_MANUAL_NAME); error = FormatMessage(nResult); end; Luckily we were already storing the datapath selected during the install in the registry as we need it when the program runs so i can use that as the destination. Getting the source path proved more challenging as the installer thinks it is running from a temp directory as that is where it is extracted to. In the end i found the SETUPEXEDIR which points to the actual exe location. ... View more

I have finally got around to trying this (ran out of actual work to do!!!) and have made progress function CopyUserManual(hMSI, destDirectory) NUMBER nResult; STRING error; STRING sourcePath; begin sourcePath = SourceDir; nResult = CopyFile(sourcePath ^ USER_MANUAL_NAME, destDirectory ^ USER_MANUAL_NAME); error = FormatMessage(nResult); end; There is a path set during the installation that holds the data files and the User Manual needs to go in there as well. If i put in a proper path instead of destDirectory it works fine, however i need to pass that value in from the installer. Is there a way to do this? Thanks ... View more

Thanks for the reply, basically yes that is what i am attempting to do I was afraid that was the answer, unfortunately this is a requirement from higher up and was dumped on my desk!!! I requested a reason at the time as to why the user manual could not be produced in time to go with the release and there has been no answer!!, not really a surprise though Looking at my options i think the best is the custom action route, our installer is only about 200MB so there is no issue on size at all Thanks for the additional actions regarding uninstall as i probably would have forgotten about them Regards Ross ...
