Basically, this particular installation problem is related to a particular user account setting. I first found a post in the Corel forums by a user having the same problem with VideoStudio Pro X3. After a lot more searching, I found that in addition to VSP X3 and X4, the same problem can crop up with PaintShop Photo Pro X3 as well. Eventually, I found a more detailed answer on the Corel website – but I have to say, it took a lot of searching. So, while the problem may not be that common, it seems worth the effort to repost the details for others who are having the same issue and can't find the answer.
If you can't install Corel VSP because of this issue, there are a couple of ways to fix this problem. Both are summarized below, but you may want to refer to the Corel link provided in the References section at the end of this article for more details.
Method 1: Since the problem is related to the settings for an individual user, probably the easiest thing to do is to create a new user with full administrative rights and install the program while logged into that account. This way, you don't have to worry about changing any of the settings on your primary account – which can be a little dangerous if you're not comfortable working with the Windows Registry Editor.
After you install the software in this new account, you can log out of it and log back into your primary account. There's no problem with actually using the software in your primary account – just the issue with getting the program installed in the first place.
Method 2: If you're familiar with the Windows Registry Editor, you can make a manual change to the Registry instead of creating a new user account solely for the purpose of installing VSP. If you choose this method, please be sure to back up your Registry first – just in case.
1. Open the Registry Editor (if you're using Windows 7, you can do this by clicking the Start button and typing regedit in the Search box, then hitting Enter).
2. Navigate to the following folder:
3. Within the Zones folder, look for a subfolder with an L or a square beside it. This subfolder should be at the top of the list, before the folder labeled with a 0. Delete this folder. (Remember, you should export the entry or make a full Registry backup before making this change.)
4. Exit the Registry Editor. You should now be able to install VideoStudio Pro.
I chose Method 2, and it was a quick and easy fix. After that, it only took a few minutes to install VideoStudio Pro X4, and I was up and running.
