File Permission Problem after 12.5.30 Update 14

[testttt]

Plesk ugraded itself to "12.5.30 Update 14" today. But after this update I can not change permission of files in subscriptions. It gives this error:

Error: File exists. (Error code 80) at GetTempFileName in C:\Windows\TEMP\
at (tempFileName line 143)
at execute "C:\Program Files (x86)\Parallels\Plesk\admin\bin\filemng.exe" mydomain.com --permissions --set-common "--file=C:\Inetpub\vhosts\mydomain.com\httpdocs\font" "--xml=tmpD1FB.tmp" --inherit-from-parent(RunTime::RunAsUser::run line 221)
(Error code 1)

I tried it with different folders in different subscriptions but it didnt change. How can we solve this problem?

It is solved. I deleted all tmp*.tmp files in C:\Windows\TEMP\ (There were 65.535 *tmp files, may be it reached the limits). After deleting .tmp files I tried changing permissions again, and it is done.
