Description (Click to toggle Visibility)

The rFactor 1255 F Patch includes:

- Security fixes for online racing
- Vastly improved game performance vs 1250

The 1255 patch also synchronizes all rFactor players - DVD & electronic.

rFactorCentral strongly recommends all players and all leagues update to 1255 F.

NOTE: The 1255 patch requires rFactor 1250 to be installed.


There are three scenarios re applying the 1255 F Patch:

- Currently running rFactor 1250, or
- Currently running an earlier 1255 patch, or
- Currently running DVD rFactor

Currently running rFactor 1250

Going from 1250 to 1255 requires one Trymedia activation. (Contact ISI or Trymedia if you require an additional activation)

1. Locate your rFactor purchase receipt including your activation code

2. Download the "rFactor 1255 F (Full Update)"

3. Back up your rFactor Trymedia license folder*

4. Unpack the 1255 F patch

5. Look at the contents of the 1255 F patch

- rFactor.exe

- rFactor Dedicated.exe

- NetCommUtilPlugin.dll

- Sounds

6. Back up those same files in your rFactor 1250 Install

7. Install 1255 F by overwriting files in your 1250 Install

8. Run rFactor. You will be asked to activate

9. Follow the Already Paid link and enter your activation code

10. Following activation, back up your new Trymedia license folder

Currently running an earlier 1255 patch

Even though the Exe Only update would do the job re updating an earlier 1255 patch, RFC recommends downloading and installing the official Full 1255 F Update, just to be sure you are completely in-sync. No reactivation is required when updating from an earlier version of 1255.

1. Download the "rFactor 1255 F (Full Update)"

2. Unpack the 1255 F patch

3. Look at the contents of the 1255 F patch

- rFactor.exe

- rFactor Dedicated.exe

- NetCommUtilPlugin.dll

- Sounds

4. Install ALL 1255 F files

Currently running DVD rFactor

If you have purchased the DVD version of rFactor download the DVD 1255 F Patch and install ALL files. Do this regardless of whether or not you applied the DVD 1255 D patch.


NOTE: Be sure to install ALL files when installing the 1255 F patch, including the NetCommUtilPlugin.dll

You can easily swap back and forth between 1255 and 1250 provided you have backed up your Trymedia folder as instructed.

* rFactor Trymedia License folder is located at (Windows XP):

C:\Documents and Settings\All Users\Application Data


Problems launching rFactor? Instead of using a shortcut, start rFactor by running rFactor.exe directly

jakobdylan on Nov-15-2011

when the update is installed does the version number show as 1255f or 1255 as mine does?

Guess I'm just dating myself... permissions now privileges then..

Try saying "permissions are a boon to the general user!"?

Oh... you do need to be running with Full Administrative privileges for activation to work, and deleting the Trymedia folder before reactivating has been known to help.

The easiest way I know of the find your Trymedia folder is do a file search for *.lcn

This Trymedia page may help with reactivation

As for the 1.255 update, there are two versions, one for the DVD version, one for the downloaded version. And despite my buying rFactor on disk, I had to update with the electronic version, not the DVD version. It can be found here marked as v1255 Update (second on list).

And, the last time I had to reactivate, I could not do it via Firefox, I had to do it with IE.

Aye the link is for the RaceSimCentral Forums which unfortunatly have had their data wiped by the datacenter they were using.
they are currently in the process of using a data recovery firm to get it all back.

Check this link

Perfect, I come back over a month later to a bad link. Well meanwhile IRacing has been a lot of fun and very easy to use but I wish I could play online with Rfactor.

Update to 1.255 by putting the files in your rFactor root. The .exe you're trying to run isn't some kind of installer or updater; it's the actual game application, which looks for the DLL in question as part of its normal program flow.

I'm trying to update as well but not sure where to go from here. I downloaded the update, made backups of said folders and located my license number in Trymedia folder but when I enter it, it says not the right number.
I can't remember if it's a downloaded version or disk version since I think I d/l first but I also have the disk form my G25.
What should I do next?
