TRANSYT 12: Path/File access error” or “Run-time error 75. Path/File access error when run is attempted”
In the case of the first error your data file is probably set as a read-only file. This can often occur without your knowledge as files stored on a CD-ROM and then copied back onto a PC will automatically have this file attribute (property) set. The solution is to right-mouse click on the file and select ‘properties’. De-select the Read-only attribute.
In the case of the second error, this can be caused by TRANSYT not being able to empty the temporary folder “T11temp” or “T12temp”. This folder is emptied after every run of TRANSYT. Read-only files in this folder or restricted read/write access to this folder will cause this to happen. The solution is to firstly delete any files remaining in the this folder – if this does not cure the problem check that you have read/write access to the folder.
