A:
Windows Vista Users
1] Exit from Steam.
2] Go to C:\Program Files\Steam\ (or your default Steam location).
3] Right click the Steam.exe and choose "Run as Administrator" to launch Steam.
The option may not work with a Desktop shortcut to Steam so be sure to use the direct Steam.exe.
This process is not permanent. If this corrects your issue, you can continue to launch Steam with this process or upgrade your Windows User account to Administrator status.
Troubleshooting Steps
1] Exit and restart Steam
2] If the issue persists, exit Steam and rename the ClientRegistry
?.blob and restart Steam
3] If renaming the ClientRegistry
?.blob file does not resolve the issue, please exit Steam and delete everything under the Steam installation directory except
Steam.exe, the
ClientRegistryOld.blob, and the
/SteamApps folder - this will force Steam to update when you log in
4] If the issue persists, please see question 1 on Verifying Game Cache Files for instructions to repair your game cache files.
5] If the issue persists, please try launching the gRailWorks.exe directly from its installation folder: C:\Program Files\Steam\steamapps\common\railworks. You may also try RailWorksProc
?.exe in the game folder to see if a different error message is found.
6] This error could also be caused by having certain Steam files set to Read Only. To resolve this:
- Exit Steam.
- Navigate to the directory where you installed Steam. (Typically C:\Program Files\ or C:\Program Files\Valve\.)
- Right-click on the Steam folder.
- Select Properties.
- Check the Read-Only? checkbox and press Apply.
- Uncheck the Read-Only? checkbox and press Apply.
7] Double-check your router configuration to make sure that it is properly configured for Steam. If bypassing the router by connecting directly to your Cable/DSL modem allows the game to work correctly, then please consult the Using a Router with Steam topic for more detailed instructions on configuring your router.
Data Execution Prevention
1] Go to Start > Control Panel > System > Advanced > Performance > Data Execution Prevention.
2] Select "Turn on DEP for all programs and services except those I select:"
3] Select "Add", navigate to C:\Program Files\Steam (or your default Steam directory), and add Steam.exe to the exception list.
4] Additionally, you will want to add RailWorks
?.exe. This is located in Steam\steamapps\common\railworks
