InstallAware

Guys, could someone explain why my snippet below does not work? I check if a file exists and it successfully returns TRUE to variable DLLEXISTS. I then check the variable returned and if it's TRUE I then run a DOS command that renames the file. I do this before the Apply Install is run. If I manually run the command in a DOS window it works and the DOS %errorlevel% result is 0, confirming it works. But if I run the command using the Run Program As statement, it does not. It returns error code -11. I'm a bit stumped. Can anyone explain what I'm doing wrong?

[DEFINE WEB MEDIA P1 - Cache sockets break-fix]

Set Variable DLLEXISTS to
Does File Exist C:\\Program Files\\ACE cache\\ACE.Apollo.Framework.CacheSockets.dll (get result into variable DLLEXISTS)
if Variable DLLEXISTS Equals TRUE
Set Variable COPYRESULT to
Run Program rename "C:\\Program Files\\ACE cache\\ACE.Apollo.Framework.CacheSockets.dll" ACE.Apollo.Framework.CacheSockets.dll.PreP1BreakFix, startup in folder "C:\\Program Files\\ACE cache" (WAIT, get result into variable COPYRESULT)
MessageBox: Copy result, $COPYRESULT$
end
[compiler if Variable BUILDMODE Equals PATCH]
Apply Patch (get result into variable SUCCESS)
[compiler else]
if Variable ADVERTISE Equals TRUE
Apply Advertised (get result into variable SUCCESS)
else
Apply Install (get result into variable SUCCESS)
end
[compiler end]
Set Variable PROGRESS to 100
end

I also tried another approach. I have an existing file called C:\\Temp\\1. In bold below are the statements I'm using. On the Apply Install I move file 1 to file 2. That works and file 1 was moved to file 2. On the Apply Uninstall I then move file 2 to file 3. However, that does not work. I reckon I'm being a dork but I'm not sure what to try or do.

There's an exact help file topic discussing this Please read "setup commands preceding Apply Uninstall" for a detailed overview.

Michael,

I shall do so. I got a bit buried with things at work to do today. I did not have the luxury of time on my side. Now that I'm home, I can chill out and research what you mentioned.

Also, please take a look at the MSIcode whitepaper. It contains an even more in-depth discussion of what you are experiencing.

I'll read that again as well. I was also thinking about the call dll function. Some years ago, I used to have Dan Appelman's (???) book on the windows api. Do you know of any web sites that have something equivalent and which might have code samples as well?

On API calls - our built-in samples have some great examples for copying files, etc. directly via the API. Just check them out - the embedded comments on top of each sample discusses techniques exposed in the sample, so it will be easy to find and well worth your while!
