Riddled with more problems than a target is with bullets...

Twice, in fact.

As I have said before:-

Your school is imposing restrictions that are stopping OR from running.

[MP36PH3S]

OR still ran until about two months ago. The machine I run it on was modified for the school network a year and a half ago, before I even downloaded OR.

The time period doesn't fit.

I have been looking at the error message you are getting. It happens to lots of people, with different versions of .net and different programs using it. Some are homebrews and some are commercial packages. There is no single thing that can be pointed at to sort it out. It would seem that OR is trying to open a form and .net/windows cannot comply and throws the error. The fact that you seem to be the only one with the problem definitely suggests that the source of the error in on your computer, and lies in how the three elements, Windows, .net and OR, are interacting. Does plain vanilla MSTS work?

[MP36PH3S]

No it doesn't-but that's because I have to fix all the 3DTS Cajon Pass and CPA1 consists (didn't have time to install rolling stock or swap out the units). I deleted all the consists and the route and MSTS works fine.

https://www.trainsim.com/vbts/showth...mework-3-5-SP1 post #2 has a link to a test tool, checks to see if .Net is properly installed.

[MP36PH3S]

Thanks for the link! Finally found out something from the log:
"Not adding product '.NET Framework 3.5' because it is not currently installed"
Kicker is .NET 3.5 SP1's files are all there-probably something with Windows itself then-during the process of installing the updates I didn't get any error message but the system shut down directly after installation with no "Shutting down" message. When I restarted it Startup repair was launched.

My install test gives the same,

[03/11/12,18:07:33] Install state for .NET Framework 3.5: installed with service pack 1.

[03/11/12,18:07:33] Not adding product '.NET Framework 3.5' because it is not currently installed

[03/11/12,18:07:42] Starting verification for product .NET Framework 3.5 SP1

Note that .net3.5 is considered as not installed because it is superceded by the service pack install.

I take it that you got "Product verification succeeded" at the end.

[MP36PH3S]

Yep. Guess it's recovery disk time...

I just read this thread even though its a few month old. I wanted to throw in something I discovered last weekend when I rebuilt my laptop. I'm a developer and at work we have several products on different .Net versions, 2, 3.5 and 4. I reinstalled Windows 7 and when I installed the .Net frameworks it wouldn't install 3.5. I did some searching for a bit and it turns out that the 3.5.1 framework is part of the Windows 7 OS which is why you won't see it in the installed programs list in Programs and Features. It's also why it shows up as a Windows Feature and you can turn it on and off with the checkbox.

I had the same problem it would not install...as it turned out because it was already installed.If you can if u can turn it on in windows features it should be there and usable even though 3.5 does not show in windows explorer or add/remove programs but other version are shown.
