Parchment Background Image for RCT3 FAQ: The Failed To Open File Error on

Some of us in the community may at times find it necessary to reinstall RollerCoaster Tycoon 3 and because we've taken our back-ups seriously we have very little trouble doing so.

However, sometimes after such a reinstall we may get the following message each time we launch the game or try to access some of our game resources during game play:

Error Message: Insufficient Access Rights Illustration for FAQ

The insufficient access rights problem is usually due to the data contained in three of the files we moved over from our old install into our new install. This FAQ will help determine if we need to make any adjustments to those files, and will next explore another possibility as to why we may be experiencing this error.


The Fix:

After we have ensured RCT3 is not running we need to go to these locations on our system:



Documents\RCT3\Start New Scenarios

Inside each of those folders is a file named RCT3.fc. The game engine creates these files each time we save a park, a structure, or a scenario that we've begun. Depending on what we have or have not done so far with our game before we reinstalled it we may not yet have this folder in Structures or Start New Scenarios.

Let's start with our Parks folder. Copy and paste the FC so we have two files:


RCT3 - Copy.fc

On the copy, change the file extension from .fc to .txt.

Next open the FC with Microsoft Notepad as if it is a standard .txt file.

Inside that file we will observe the system path references that were created on our old install by RCT3 so that it could compile our filesaves.

On our old install we may have had a different user name than the one we're using on our new system, or the name of the folder our files are in now may be different from the one in which we previously kept them. With our FC opened in Notepad we need to use Find/Replace (up at the top in the Edit menu) and replace all our previous system path references with our new system path references.

The two sets of data we're interested in are the user name and the folder name so, for example, if on our old system we were

C : \ U s e r s \ J a c k \ M y D o c u m e n t s \ R C T 3 \ P a r k s

and on our new system we are now

C : \ U s e r s \ J o h n \ D o c u m e n t s \ R C T 3 \ P a r k s

we need to replace all those Jack\My Documents references with John\Documents references. Note that the text in this file is written so that there's a space between almost every character, so when we type in our replacement text we need to ensure that we type it in this way

C : \ U s e r s \ J o h n \ D o c u m e n t s \ R C T 3 \ P a r k s

and not this way


Don't overlook including the space after the word Parks .

After we've made all the changes we'd close the file that we just changed. Next we'd move the original RCT3.fc file from the Parks folder to our Desktop where we should put it into a new folder and identify it as the one we moved there from our Parks folder. After that we'd return to our Parks folder and change the name and extension of the file we just edited, changing it now from RCT3 - Copy.txt to RCT3.fc.

Next we'd repeat this with the FC inside our Structures folder and then with the FC inside in our Start New Scenarios folder. After we've completed this with all three FC's we may launch our game as regular.

While it's always best to keep the files we found and to attempt to work with those, as with our Options.txt files, if we are unable to fix this issue with these FC's they may be deleted, after which the game will create new ones during our next save.


After Windows Vista ... Libraries

Made possible since Windows Vista by way of a new document storage system and a new set of document reference values, libraries were introduced as of Windows 7 because Microsoft observed that most individuals keep files all over their PC's and not in any single location. Often these users would want to return to a file they had created only a week prior, couldn't remember where they had stored it, and as the file hadn't been stored in any of the designated user profile folders, the file therefore had not been indexed by the system and was difficult to find. Libraries permit users to store files wherever they desire on their PC and give users the convenience of all their files being in a single location while making it much easier for users to organize, find, and edit these files.

In view of that, another reason we'll get a file permission error in RCT3 is that we've moved our files into the wrong folder when restoring our backed up files to RCT3 after re-installing the game on an upgraded platform. If we've upgraded from XP or Vista into Windows 7/8/10 we will want to be sure we've moved our RCT3 saved documents (Parks, Coasters, Structures, etc.) into

C:\Users\[USER NAME]\Documents

and not into


Even if we have the same user name on our new install as we did on our previous install, Libraries\Documents is actually a logical (virtual) representation of a single folder location and not an actual location. Items placed inside Libraries\Documents are actually referenced and indexed by Windows as if they're placed in

C:\Users\[USER NAME]\AppData\Roaming\Microsoft\Windows\Libraries\Documents

So if we've made the above recommended adjustments to our FC's and are still getting this file permission error we'd want to be sure of the location of our RCT3 Documents folder. To do that we'd simply go to


And move our RCT3 folder from there to another location, e.g., our Desktop, our Downloads folder or our Favorites folder, and then move our RCT3 folder from there to

C:\Users\[USER NAME]\Documents

As the final step we'd restart our system to give Windows the opportunity to make any back-of-house changes that may be necessary.


After reviewing these options and making any necessary changes such file permission errors will become a thing of the past.
