PE 16bit subsystem error and "Error 52"

I have some strange errors that i havent seen before. All this began after installing Autodesk Inventor Professional on the workstations as our school uses both bits of software.

Programming Editor opens correctly but when any code is run a message comes up saying that a file in C/System is not suitable for running a 16bit subsystem. Closeing this error a new error opens with a message "Error 52" and after closing this box another error pops up saying the path to the programs install folder is "Invalid".

I have tried all kinds of things, permissons and such like but cant get these errors to clear. Uninstalling Inventor is the last option as its needed.

Anyone got any ideas?

Thanks in advance.

The 16 bit subsystem implies use of the 'original' compiler - try using View>Options>Editor enhanced compiler, and the problem might go away anyway.

The feature seems disable. We're running the latest version, but it doesnt work.

I am not familiar with the software, just trying to fix it for a teacher. Is there a particular reason why features would be disabled?

Thanks

Enhanced mode is available for all PICAXE chips. Select the PICAXE chip mode first (e.g. 08M on the Modes tab) and then go back to the Editor tab.

Your system is rejecting 16 bit files, some networks like RM CC3 do this, but can be changed. Look at step 6 here

However the enhanced compilers are 32 bit anyway, hence no 16 bit issues.

It could also be this issue described here:

AH! the second one, i think thats exactly the problem , the message is certainly one of the ones i'm getting.

I will look into that, thanks for the help

EDIT: Fixed, many thanks!
