Tips, tricks, and guides for developing on modern Windows platforms
I have recently had the following error when trying to debug my apps on the Windows phone emulators:
The error tells you what the problem is: “The emulator is unable to create a differencing disk”, and gives you the first part of the solution: “Virtual hard disk files must be uncompressed and unencrypted”, but doesn’t tell you which files need to be uncompressed and unencrypted.
In my case my C: drive is compressed.
The folder that needs to be uncompressed is:
C:\ Program Files (x86)\Microsoft SDKs\Windows Phone\
It contains the emulators for the different versions.
In my case I believe that I also had to make sure the following path was not compressed:
C:\Program Files (x86)\Windows Kits\10\Emulation\Mobile\[version]
(I can’t know for sure because I gave up and uncompressed the whole drive before I realised that folder might be the issue)!
