i’m not a programmer and I just wanted to make a installer for “unpacking” folders with files to a specific location – I done it with the Inno setup wizard, but there is an issue because I would like to first check if folders with the name already exist, and if so rename the new ones:

I’m trying to create a Inno Script that allows the definition of multiple installation folders. This script also needs to set the ENV path variable to the main directory installation folder. To achieve the later I have use the modpath.iss script that I have a coupl of years ago here somewhere and to achieve the first I have taken references from this two questions:

i got a question, it is possible to show elapsed/remaining time and percentage of decompression with unarc.dll ?

I am using innosetup for the installer, which loads external dll created for my application which is Win32Library.dll & some other stuff, but while deinitialize , i am getting errors like it is unable to remove that directory.
