Error code running a DOS command.

[bokkie]

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?

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.

[MichaelNesmith]

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?

[MichaelNesmith]

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!
