Unable to save Microsoft Office 2013 files on RAMDisk anymore

Hello experts,

maybe you are having an idea, what might be the cause for this and know or can point me to the solution.

Windows 10 (German) - RAM Disk 3.7.4 (64 bit)
I am having Microsoft 2013 (German) on an Windows 10 Laptop (German - Hardware Laptop) installed.
Am having 16 GB RAM and gave RAM Disk 4 GB. I am using NTFS for my RAM Disk and simulate a HDD.

When I want to save a Microsoft Office Document, like Word, Excel, etc. on the RAM Drive, I am getting an error message, Office is unable to save the file. Of course I am able to save the file, on the disk drive.

As I am able to save a picture, done from Paint Program, on the same path in RAM disk, I guess, there must be a setting or security function active, that blocks me, from saving the file.
I am able to copy Word, Excel files to the RAM Disk, I am able to open them, but I am unable to save them. When I do so, I am getting, for example from Excel, a dialog box, that informs me "... Error when save the file. Removing or repairing some features, Microsoft Excel might save the file. Click on continue, to start the repair into a new file. Click cancel to interrupt the file saving process ...".
The message is in german, so not sure, if a screenshot will help ...

Some months/weeks ago, I was able to write the Office files, to the RAM Disk, so it might be a issue with RAM Disk, as I installed some months/weeks ago the latest version, or a patch/security setting inside office, is blocking it. I tried to uninstall RAM Disk and reinstall it, but this did not resolve the issue. Also using FAT32 is not solving it.

My temp variables are on default.

I was looking via Dr. Google for a solution, but haven't yet found something usefully.

Many thanks for your help.

Best regards,
Carlos

I think it may be related to certain disk I/Os that are not fully implemented. Please see this topic: a user was unable to create VHDX files, though VHD files were created fine when Hard Disk Emulation was on.

What happens if you try the Hard Disk Emulation off?

Hello Andrew,

Perfect!
Your hint works.

Many thanks for your help.
