Having used the 98SESP for some time now, I recently came across this forum, & hence Tihiy@s Revolution pack. Finally got around to installing it (RP4 build 2700) today, & apart from a few "common" problems (mainly around shdoc401.dll not registering), am well impressed; with one serious exception: I know it's daft, & I should know better, but I've gotten so confident that judicious use of scanreg /restore & a few other trinkets will dig me out of any system- related problems, that I no longer bother religiously backing up my system before major cosmetic surgery such as the Rev Pack, relying on a comprehensive tree of old rb00x scanreg backups, ++ a few other tools & backups, all of which are conveniently stashed inside the sysbckup folder, & which have managed to get me out of just about all my frequent cock-ups & crashes. Until this crazy bloody installer of yours ran it's makbackup batch file, supposedly to add a bit of security to the whole process, & promptly ran "deltree /Y %windir%\sysbckup" WHAT !!!!! why the hell do you have to do that ???? Without warning, or choice ????? Couldn't you at least have backed it up, or given me the option to abort, first ?? That's it, gone. all my registry exports, dll file backups, old registries, even (just to add insult to injury) my bloody "undelete" utility. And then promplty recreate sysbckup just to make sure that by the time I'd got over the shdoc401 crashes & VFAT conflicts to get 32-bit Winows running again & run a new copy of undelete, the original sysbkup folder, & all my extras therein, were well & truly gone for good. I can only put it down to sheer bloodymindedness.
