Got exactly the same problem. Folders in Temporary Path do not get the right permissions. Big problem!
I have this problem on Windows Server 2008 R2 after installing FMP15v2
We haven't released this update to our clients as yet due to reports of this problem.
However, we have just carried out our first test on a Windows 2012 server and have not experienced the problem, with PDFs saving to the temp folder and then reimporting or opening as per each script. However, we haven't updated any 15.0.1 on our Windows 2008 servers as yet.
Will try to do additional tests later.
We are seeing the same issue on 188.8.131.52 32-bit and 64-bit Windows.
Save To PDF in version 184.108.40.206 works as expected.
15.0.2 fixed some important issues so being stuck on 220.127.116.11 is problematic to say the least.
Has anyone from FMI commented on this yet?
