Windows 7: Fresh Windows install, but apps are saying they're already installed?

It is critical that you disconnect all drives (except OS drive) when installing Windows. It sounds like you had all your drives connected and now your programs installer is finding files on your other drives, therefore, giving you the error. Can you post a snip of your disk management window? It could help greatly. Just a thought.

Formatting is not a very good way of erasing data. Especially from windows installer.

Diskpart is the best way to get rid of old stuff on your hard drive, with the clean command. If you want to tell me that you know a bunch about computers, then look at this video, and see just how long a quick format takes, at 1:22 in the video. The drive is 2.5 GB, but you get the idea.

You guys are getting topics confused. The Windows installer is a horrible way of clearing data *securely*. It is perfectly effective at clearing away data and partitions so they don't remain after a clean install. Let's stick to what's actually going on here, and not derailing into a thread on data security and destruction.

If the OP deleted the partitions and recreated them during the install, there's no chance any leftover files or settings remained visible to the new copy of Windows 7. An in-place install....yes...but not a clean install.

To the OP, I just had a hard time with a home built gaming system, and I couldn't log in with user passwords, couldn't boot Windows 7 DVD, and many other odd problems.

Now you may not be experiencing the same, but you might have a hardware issue like a bad stick of ram.

Have you tried to run Memtest86 from a boot disk?

Here's the thread I started about my PC Problems, in this thread, 2nd post of mine are links to memtest, give it a shot and let us know. Do not trust memory test from windows, I ran it and came back fine, started to run memtest, got to the options window, selected default single core and thats as far as it would go. Started pulling out ram and sure enough narrowed it down to a bad stick.

Major Issues... The PC Not Me... I swearer

Also, as others have stated, disconnect everything from pc except mouse & keyboard & Monitor. No ext. HD's, printers, speakers, nothing but KB & Mouse & Monitor.

You have a very strange problem, choosing "Custom" clean install, should not give you problems with older programs that it "thinks" are already installed.

Good Luck

...on this one as well, you stated you have other hard drives connected internally. Disconnect them an only work with the drive for OS Clean Install.

Also mborner asked for a Disk Management "Screen Shot" & Post, if you haven't already wiped out the drives...

I am speaking from experience about data retention after formatting. I have had a computer retain ALL music, fully playable, discoverable by a media player, etc etc etc. on a formatted hard drive. I COULD NOT find the music on the drive, however. Ghost data is a problem with formatting, from a security standpoint as well as for an end user. If your data is not written over, it could still be readable to a degree that would cause problems with an operating system or other programs.

I would have to agree with you, data is not removed during a format, just un-indexed. Not talking about Windows Index, but system OS HD. index. If someone was to run a disk recovery program, you might be able to boot to it!!! (Thats not advice !)

If you have the tools, and are wiping out a drive for a new install, it is a good idea to run a program that "scrubs" the drive with like all "Zero's", as it is new, like using Drive Erase Pro, but I'm sure there are free ones or trials that would do the job.

Also, Think theres a tutorial you followed (or could) to clean the drive via a command prompt, That should be more than enough.

It is rare for existing data after a custom "clean install" for it to "find" and think its installed programs, ...It's a first for me, but for the most part a format and clean install is usually enough not to have issues. Still might be able to recover with a software app, but for the newly installed OS to think programs are installed when not, thats really weird.
