Adobe Acrobat on Windows 8.1

ArrunG's solution worked for me too.  To disconnected your login from your Microsoft account go to Settings>Account>Your Account and check the disconnect box.

question only for you:

do you change everytime your car, tv, girl or anything else when the calendar changes? ;-)

win 8.x can simulate older Versions like win xp.

I tried to run Acrobat in win xp mode but it doesnt work. Mmmh...

It's entirely up to you if you want to install older apps which will expose your machine to attack. It's your property and you're entitled to do whatever you wish with it.

All I can do is to point out the dangers of doing so and then it's up to you whether you wish to disregard my advice or not.

Just don't blame me when malware takes advantage of flaws in older apps and empties your bank account for you.

You're really asking for trouble installing an old version of Acrobat. Here's a list of all the vulnerabilities which can compromise your machine which date back to 2009 when that version was released. http://helpx.adobe.com/security/products/acrobat.html

If you want to continue using Acrobat, then update to current version a.s.a.p., or switch to the free Foxit Reader which you can download from here:
