We are rolling out a new forum structure to replace the Windows 10 Technical Preview forum. Start posting your questions and discussions now in the new
Windows Insider Program forum.
Were you able to run the program earlier?
I would suggest you to run the program from the USB hard drive itself where the installation folder of the program is present and check if the issue reappears.
For now, let’s follow these steps and check if it solves the issue.
Change the drive letter assignment for the USB drive to a letter other than C.
1. Log on to the computer as Administrator.
2. Insert a disk in the removable drive.
3. Type computer management in the start search box and hit Enter.
4. Click Disk Management.
5. Right-click the partition, logical drive, or volume that you want to change, and then click
Change Drive Letter and Paths.
6. Click the removable drive, click it, click
Change, click the drive letter that you want to use, and then click
Hope the information helps. Please post back and let us know.
