Is this a new C: or a new install on your formated C: ?
Downloaded ArmA or in a box?
Vista or XP?
Other games install without problems?
Whatever, go get CrapCleaner,(read the readme) run the Registry Tool and see if you have any ArmA lines that need to be fixed/removed.
Might help, might not.
Thanks, I wasn't expecting help - just sharing my despair as i was really looking forward to starting a good arma session.
OK had hardware problems which cuminated in to total failure of my C: drive... (i use small C:'s containing OS ( WIN XP home), drivers and a few vital small progs antiv etc. and install games/large programs to larger drives)
so it's a new c: that had a bare set of drivers on it, since updated, except the mobo's sata i think..
However replacing with this drive meant i couldn't run Arma due to now-missing doc&sets Arma files i guess, nor could i uninstall the game, so i did this manually (yes poor i know, but had little choice and with the origional C: now missing i figured less a problem)
I have reinstalled some other games sucessfully but thinking about it they were all older games many of which i could unistall with launchers and/or didn't use the c: docs & setts for vital info like the cd key info , savesgames etc.
I imagine this sketchy process has the potential to cause problems- and crap cleaner is probably a good idea- i used it once for something else and it worked well.
Thanks for advice - i greatly appreciate any help. Just got back from night shift and off to bed -later today i'll get into it all fresh and envigorated...
