I do not work for VDH. I'm just another user.

I ran VDH on Windows 7 for a few years without problem, although that was on a 64-bit W7. Just crossing Ts & dotting Is, you must be certain to get the "right" version of the CoApp for W7 32-bit. I'm going to assume you did that. In that case, the error messages you're getting suggest to me that you do not have sufficient permissions to make the updates on your Windows boot partition. If you are the only user of the system, you ought to go through the rigamarole of taking ownership of the entire boot partition. Take ownership. That's Microsoft jargon. If you don't know about it, web searches will turn up everything you need to know on the subject. Typically, I have always found, even now on W11, that this ownership boondoggle puts up a couple of error messages. I've always just ignored them & let the take ownership process proceed as far as it is willing to go. You should then retry your installation of the CoApp. If you have another partition in your system, you might try installing the CoApp there. I would assume that any partition that is not C: would be properly "owned" by you & all attempts to update there would work fine. There is no requirement that the CoApp be installed in a directory on C: nor that it have any particular name. The whole thing is, as far as I can tell, controlled from an entry in the Registry that gets written by the CoApp install program.

There is a possibility that your antivirus is interfering. When I was on W7, I used to use a free AV program called Comodo. When I got to W11, I was prepared to continue using Comodo but I discovered there was an AV built in, so I just started using that, keeping Comodo as a possibility for later. Well, later never came. Whenever anything has ever triggered the AV, I just tell it to go ahead. The error message from the AV is just a false positive. Telling AV programs about false positives is a routine annoyance. Just do it. There is advice in the Wiki (link at the top of every page of this forum) on the subject of AV. You should read that.

I hope there's something helpful in all of that. Do post back with your further experience.
