I have been trying to package a VB6 app using Inno but it generates the following error:

The process cannot access the file because it is being used by another process.

which points to the EXE file. I can't seem to find any other process using the EXE & to ensure that as far as possible, I restarted my PC after which the first thing I did was compiled the Inno setup file but it still generates the above error.

Any idea who could be using the EXE? There are some registry entries for this app. Could that be the cause?

I am on WinXP SP2. I tried compiling another EXE using Inno & it compiled successfully.
