I have an old legacy application around for which I only have the installer. it doesn’t do anything more than uncompress and register itself and his library’s.
As i don’t have the source-code it gives me a lot of headaches in maintenance problems. In some particular computers (Acer Aspire One with Windows) just do not run.
I would like to extract the files and re-create this installer with NSIS. Is this possible or I’m nuts?
The original installer has been created with Ghost Installer Studio.
One option is to find a machine that it does run on, and then install some ‘install guard’ software (often called things like Acme Uninstaller). Use this to track what actually gets installed and then copy the relevant files and write your own.
It looks like a lot of hassle to me, and you may be on thin ice with regards to the licence.
