FFS Crashes on Win7 64bit

[tristan-heuer]

FFS Crashes when I start File Synchronization. I have tried versions 6.8, 6.7 and 6.6 (portable and installation).
I am running Windows 7 64 bit. FFS used to work fine on my system.
However after formatting and re-installing Windows it no longer works. Does FFS rely on any libraries or something like .net?
I tried running in batch mode and enabling logging. It crashed, however the log was empty.

Does FFS create a crash dump file automatically? Is the crash reproducible and what are the steps? If yes, can you send me a mini dump file created with Process Explorer for the FreeFileSync_x64.exe process?

How do I know if FFS creates a crash dump file?

How to reproduce the crash (crashes every time for me):
-add folders to sync (or load profile)
-click on synchronize
(start synchronization now? pops up)
-click on start
(synchronizing... pops up)
-and then before any files are synchronized it crashes and the "stopped working
dialogue show:

I have attached a mini dump file (I made the dump after FFS crashed)
I have also added a screenshot.

If there are no files to synchronize or I deselect them no crash happens.
And synchronization completes showing the completed dialogue as normal.
(see attached screenshot)

I noticed I didn't do the dump from the x64 process. Here is the correct
dump file

FreeFileSync crashes at the following assembly instruction

000000013FAC40F3 vpsrlq xmm3,xmm0,34h

That's from the AVX2 instruction set and your CPU doesn't seem to support it. What CPU do you have?

Are you on Win7 Without SP1?

[tristan-heuer]

My CPU is Core i5-4670.
Yes, seems I don't have SP1. I recently re-installed windows and though I installed all the updates through Windows Update. It didn't however, so I manually checked for updates and am installing now.
After getting SP1 I'll let you know if that fixes it.

[tristan-heuer]

I have installed SP1 and FFS works now.
Thanks for your help.
