A 2502 error is a result of Microsoft, not giving permissions to the temp folder so that it an application can extract itself and run from that folder. It has nothing to do with Race Manager Sqorz, or the API. Here is one solution to try.
To resolve the issue, do the following:
Navigate to File Explorer location: C:\Windows\TEMP
Right click on the TEMP folder and select "Properties".
Select the "Security" tab.
Then select the "Add" button.
In the "Enter the object names to select (examples):" table, put in (without quote marks) "EVERYONE".
Then select the button "OK".
Then in the "Group or user names:" location, select the button "Edit".
For all Group and user names, allow "Full Control".
Then select the button "Apply".
Launch the product.
FYI: When you buy a new Windows computer, Microsoft requires you to create a Microsoft account to log into the computer with. The problem with that Microsoft account is that it does not always assign permissions correctly to the file system and the issue you’re encountering is because you do not have rights to the temp folder to Unpackaged the program installer into.
