Run the game without installing?

<< < (4/4)

Lord Darcy:
I used to do the same thing as OP in TS1 days. I always installed TS1 to my data partition, not the program partition, so all installed game files were intact even after formatting and reinstalling Windows. With the single execution of the exported reg file, the game is magically reinstalled again... how sweet.

I was severely disappointed to find that this trick no longer works in TS2. Tried and failed. I had to manually delete all added entries. I was not sure whether it's inherently impossible in TS2, or I missed to export all needed registry entries.

I am one of those neurotic people who tries to keep a nice cleaned up registry. To make that easier, I use Revo Uninstaller to rid myself of all those weird leftover examples of hexgibberish whenever I uninstall anything, but there are other programs which do the same thing. I have noticed when uninstalling programs with Revo that it often finds keys I would never have located myself. If you missed any keys you could probably find them by using one of those programs, but Revo forces the user to uninstall with the program's own uninstaller before it performs deeper searches for leftover material in the registry. For that reason, you can't use Revo to find them without actually doing an uninstall. Unfortunately, I do not know if any similar programs can show you those without performing an actual uninstall. It might be worth looking for one. You may be able to find some keys you missed exporting.

Yes, there are keys:
HKEY_LOCAL_MACHINE\ Software\ EA Games
HKEY_LOCAL_MACHINE\ Software\ Electronic Arts\ EA Games
HKEY_LOCAL_MACHINE\ Software\ Microsoft\ Windows\ Current Version\ Uninstall
You'd need to extract all of those from your current install, and then install to the same location to make them work on a new install. I'm not sure if there are any more entries lurking anywhere, or if the keys are different in Vista.

Yes,two more registry entries needed:
[HKEY_CURRENT_USER\Software\EA GAMES]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths]
Then all goes without any problems.But if you install(add) some new EP or SP you need to export all 5 registry entries again according to changes
I keep my "open"game install on 3 DVD and reinstall it on fresh system(after system crash as usual) really can save time and nerves. :)
