Hi all,

I'm trying to get OR installed properly on my Win 7 computer and the one d/l I'm having trouble with is Net Framework 3.5. When I try to run it under Administrator it will start but then I get an error telling me to use the control panel/programs/use the 'turn Windows features on or off'. It seems if I leave the 3 boxes unchecked its my best choice. Are these boxes supposed to checked? My control panel shows that I have Net Framework 4 but no 3.5.

When I try to load OR I get the message that OR needs Net Framework 3.5 to run. I'm stuck until I get this fixed. Any help will be greatly appreciated. Thanks.

Again, I've found that an earlier version of Net Framework will not install if a newer version is already installed.
I always un-install all Net Frameworks and re-install the earlier versions first.

.net 3.5 sp1 is included in Windows 7.
And it is updated with windows update as required.

Don't know anything about Win 7 but in XP you can go into the Control Panel>Add/Remove Programs and look to see if it is installed on you system.

As it is a native part of win 7, it does not appear in add/remove programs.

It does however appear in "windows features".

Windows 7
If you go to:-

control panel
programs and features
Turn windows features on or off

You will find 'Microsoft .Net framework 3.5.1'

It is installed by default.

Thanks for the help so far but I am still receiving the error 'OR requires Microsoift Net Framework 3.5' when I try to run OR. I do have 3.5 listed in the 'Turn windows features on or off' with none of the boxes checked. If 3.5 is installed by default in Win 7, why do I get this error?

Earl,

If it's of any use to you, here's a screenshot of what my setup looks like (click for a larger image):

I didn't have the 3.5 box selected so it now shows up in blue like yours. I tried OR and all my routes are listed but I selected an act with 3 engines pulling a coal drag and I only see the middle one. When I select the F7 key it shows I should have 3 engines and when I power them up I see black exhaust at 3 locations but only one engine showing. I must have missed something somewhere. Any suggestions? Thanks, again.
