Downloading VMSpc

I am having a issue withWindows 10 and downloading VMSpc. I have also on the PC WinZip Version 20. Not sure how to use this along with your instructions. WinZip seems to have a mind of its own. Please help, I miss not have VMSpc on our travels.

Not much I can tell you aside from the instructions here:
"To start a fresh installation..."

If this still gives you fits, give us a call so we can walk you through.

I'm having the same problem.

I'm having the same problem. I have an ASUS notebook (2010) with Windows 7 starter and I wanted to update the VMSpc software. When I did I got an error message, "Error failed to open PAMATERS.DAT", then "Error reading file Caterpillar 3126...". I uninstalled everything and started fresh, same problem. So I did what any male would do, I went out and bought a new Dell 11" laptop with windows 10. Same problem. I called the Tech line yesterday and we could't fix it and I was getting frustrated so I said I would call back today.

Any ideas?


Errors and Win7 and Win10

Hello Steve

It's not exactly clear why Windows wouldn't allow access to the Parameters.dat file. Its a normal part of the VMSpc install. There's one instance where it may balk: If you're running the the program as a basic user, not an administrator. With some builds of Windows, the privilege level is set so low as to not allow anything but a browser or game of solitaire.

This plays out when we try to refer to the Parameters.dat file to get basic setup info: What gauge-screen to use, what the save-as folder is, names of most recent trip, odometer and tank-minder status. But...Windows, at times, wants to be the only program that uses a 'data' (or .dat) file so we have to do things differently.

Run As Administrator
We use this option to tell Windows to do it anyway; give Steve access to his data file.

Run your program this way and I believe it'll work fine. Do a quick search on this site or on the web for how to do this little bit of check-box clicking. If that still doesn't help, give me a call.
