I just posted an issue with old VHDMOUNT scripts I created. As mentioned in the earlier post, this issue was caused because of an update to GetVirtualHardDiskInfo method output format. You can download an updated version of this script here. You will have to unzip all the files in to a single folder and then import HV-Reg.reg in to your registry. You may have to change the script path in the registry file based on where you have unzipped these files.
