Running Photoshop 19 on a windows 8.1 64 bit system. Everything was fine until a couple of days ago. Now Photoshop fails to initialize. Most of the time it says missing api-ms-win-core-synch-l1-1-0.dll. That will pop up a few times then then pop up a message saying "could not initialize Photoshop due to a disk error." Sometimes it just goes right to the could not initialize error. I have checked and I do have the supposedly missing dll [in both windows folders where it belongs.] I had updated an unrelated program shortly before my Photoshop problems started, so I unstalled that and did a system restore to bring Windows back to a point where everything was working. That didn't help. I have uninstalled and reinstalled Photoshop probably a dozen times now [still version 19 because I can't upgrade any further on this version of Windows.] Now I do have an old copy of Photoshop Elements that runs just fine, and all my other Creative Cloud Apps run. [Lightroom, etc - I have the photography plan.] I have scanned my harddrive for errors, I have defragged it, I have run CC Cleaner to get rid of any junk that ws hanging around. I have plenty of free space on my hard drive, and ther only program that is giving me issues is Photoshop. I have toyed with the ida of getting rid of the entire Creative Cloud suite and reinstalling, but I'm afraid I might break something else. I have also toyed with the idea of updating to Windows 10, but that seems like that would be a bigger hassel that could potentially break more things. I could use some more ideas on what to try.... Googling has not helped me much.
On rare occasions, the program is not recognizing the api-ms-win-core-synch-l1-1-0.dll, even though it is installed correctly. In these cases, the installation of the Microsoft Visual C++ Redistributable Package could help. If you are still getting the Missing Error, try installing it here.
Errors related to api-ms-win-core-synch-l1-1-0.dll can arise for a few different different reasons. For instance, a faulty application, api-ms-win-core-synch-l1-1-0.dll has been deleted or misplaced, corrupted by malicious software present on your PC or a damaged Windows registry.
The most commonly occurring error messages are:
