Have you got all of the updates for Windows 7? Windows 7 SP1 is the minimum system requirement -- though Windows 10 is the preferred OS for this program.
Yes, Windows 7 is running with all the last updates (Windows is configued to update automatically). It has not been brought to my attention before that Adobe recommends to use Windows 10 instead of Windows 7 and will stick for the time being with Windows 7. Any further clues?
I have seen no difference in the performance of Premiere Elements 14 on Windows 7 Professional SP1 64 bit versus Windows 10 Home 64 bit.
Some just in case questions....
Are you running Windows 7 Professional 64 bit with Service Pack 1?
Did you check the permissions in the file pointed to in your description of your issue - sync_util.dll and associated folders?
Did you install the program to the Local Disk C?
Are you running the programs as administrator, from user account with administrative privileges? Are you running the program with an Internet connection?
And, the usual, do your have the latest version of QuickTime 7 installed on your computer?
Please do confirm that you're running Windows 7 SP1.
Yes I can confirm I run Windows / Pro SP 1 in the 64 bit version.
Regarding the previous hint/message: Unfortunately, I do not know how to check or changes the permissions in the file pointed to (sync_util.dll). Please advise. On the other hand, this error was reported only once and not again upon the last installation process(es). Program was installed on local disk C (an SSD drive), then alternatively on D (HD) and the issue remained. Quicktime latest version is installed. I use the PC as user with administration rights.
Regarding permissions for syne_util.dll....
Please go to
Local Disk C
Elements 14 Organizer
and in the Elements 14 Organizer Folder scroll down to the file named sync_util.dll
Right click the syn_util.dll file and select Properties from the pop up menu.
Go to Properties/Security/ and determine what is checked.....for my Premiere Elements 14 that is working, I have checked
Read & execute
List folder contents
Not sure if that will make the difference, but worth a look.
Add On...for troubleshooting purposes, I would remain with the program install on the Local Disk C.
