iTunes auth problem on Windows 7 64-bit
Hi,
I experience weird issues with the iTunes auth-process on a Windows 7 (64bit) machine.
When I try to authorize my computer it results in a message telling me something about connection issues. Anyhow, it seems the computer is kind of activated since I can deauth my computer. If I try auth'in my computer several times, it also allows to deauth it several times until it says that it is not auth'd anymore.
My tries so far to solve this
- updated to latest iTunes
- deactivated, even uninstalled firewall (used NIS2011), also disabled the Windows Firewall after that
- checked hosts file
- deleted SC Info
- even tried with creating new library
- disabled User Access Control in Windows
- disabled all startup items in "msconfig"
- tried to activate with same account a different computer in the same network, I was able to play movies using the private home sharing feature, also activation was no problem
- re-installed Apple Software (including iTunes, Quicktime and Safari)
- checked Diagnostic within iTunes with no problems
So my guess is that it could have something to do with 64 bit or any hard- or software related issue at my computers side.
Detailed procedure:
1 - Start iTunes, click Store > Authorize > Enter credentials
and now the weird thing is that the "authorize" button says "deauthorize", no matter how often I try to deauthorize before.
2 - Repeated step 1 since it says always the same error message (connectivity alert)
3 - Playback of any DRM protected media does not work (movies). It asks for authorization again but fails to do so with the same message again
4 - Deauthorizing is possible and I noticed that I can do this as many times as I tried to authorize before.
Does anyone have a suitable idea for helping me out in this issue? I never had problems on my mac before, nor on a Windows 7 32bit system.
My 64 bit machine is only used with one iTunes account.
I already contacted the iTunes Support via Mail but they could not help me since this could be a technical issue.
Any help is much appreciated.
Thanks in advance,
Benjamin
