I dont know if this helps but the error message says "the file 'setup (2)-1a.bin could not be located
The "(2)" in the above name should not be there.
If you have not already, DO NOT delete ALL the files...you only seem to have a problem with one or two, and only they need to be replaced at thius time.
On the Desktop, create a new folder, name it anything you like, such as TS12DL.
-Re-download the "setup.exe" file, and the "setup-1a.bin" file to this new folder.
-Copy the other good files; "setup-1b.bin", "setup-2a.bin", "setup-2b.bin" and "setup-3a.bin" to this new folder.
-Select each file in turn, starting with the .exe file:
--Right-click on the file, select "Properties", left-click the "Compatability" tab, at the bottom check the box for "Run as Administrator".
--next, select the "Security" tab, in the middle of the window, left-click "Edit".
----In the next pop-out window, select each name listed, in turn, then in the bottom section, check the first box in the left column "Full control"-"Allow"
----Repeat...when all "users" have "full control", click "save", click "OK".
--back in "Properties" window, click "save", click "OK"
Repeat for remaining .bin files...note, some options may not be available ( .bin file properties have no "compatability" Tab), skip that step, just do "Security".
When all Compatability and Security settings have been set, and all windows closed:
-Right-click on the setup.exe again, left-click "Run as Administrator".
When the setup begins, enter the relavent information as requested, and when prompted "where" to install DO NOT select one of the "Program Files" folders:
-Instead, install directly on to the C:\ drive, such as "C:\N3V\TS12".
Continue as normal from there.
Good Luck.
