Best was to setup multiple Opera versions on OS
Now that I've reloaded a fresh install of the OS and setup KernalEx I want to continuse using multiple Opera versions. The clean install has eliminated all the software I tried but didn't find useful which helps keep the registry unclogged. In the past I'd load various Opera version into their own folders, never had a problem. But they were in the registry (bloat?). I learned that I could setup a version on one PC I used for testing software and simply copy the entire folder to another PC and the browser worked w/o having to load it from scratch on the 2nd PC (I have two of the exact same model PC's).
Question 1, is this acceptable to do w/o any problems? I've never encountered any issues but want to ask the forum experts if this could cause issues. Or, should I load each version I want to use onto the one PC, each in its own folder (Opera7.11, Opera10, Opera 12.63, etc...). I'm just looking to avoid putting any more entries into the registry than I need to. I've done this for years and even found I can take a copy of Opera on a flash drive and use it on the public library computers since they do not allow you to load software onto their PC's.
Question 2, I've used multiple versions of Netscape, I.E. on one PC at the same time also. Has anyone also simply copied a version of another browser and placed it into a folder on another PC and it works just fine? I think (too many years since I did it, can't remember how it worked) I've loaded netscape 7 or 8 on one PC and copied it to another and it worked.
Over the years I've used software for a while and then removed it for something newer or better but this gums up the registry. If there's software I can simply load on the test PC and copy onto the PC I use everyday, it seems like there's less chance of issues due to registry entries. Aida, Textpad, and other programs I use are not registered, just copied and placed on the appropriate folder, they all work just fine (so far).
