Custom Module compatibility error on module add

[danceoutfitters]

I'm new to this process, though have read through many threads for information on building my custom payment module. I put together a skeleton module with all the required functions and succesfully compiled it. I also can upload the compiled module, however when I click the add button to add the module, I get the following error:

Runtime error in 4.23/admin.mvc @ [0000000a:000000d2]: Line 2248: MvDO: Unable to open '/Merchant2/4.23/MIVA_FUP00000001': File was generated by an incompatible version of the Miva Script Compiler

I am running engine V4.14 and MIVA V4.23. I thought I read that the MiVA compiler v5 was backwords compatibe, so I'm puzzled. Any help would be greatly appreciated.

Are you using the compiler command: mvc -c 4.10 filename.mv

You need to tell it to be compatible with older versions. This is covered in the Compiler's UserGuide.

Oops missed that in the documentation.
I did compile it with the proper version, and now I'm getting an error Installation of module "1" failed.

Did you uninstall the old version and pack first?

Also, did you use mvc -c 4.14? or c -4.10?

You'll have less compatibility issues using 4.10 as the compiled version compatibility.

I used 4.10. Unforunately I did not uninstall and pack first. I choose to overwrite. Now I'm having problems on the add a module page and just keep getting error on page. I then manually deleted the module from my web site. Tried packing and logged in and out of Admin....still having problem with add a module page. Not sure what I may have done.....

Well, Module ID 1 in the modules.dbf is usually MMUI, so if you hosed that up somehow, I'd suggest restoring from backup.

I restored and also found a typo in the code. I have succcessfully loaded and installed the module. so now it's time to test & test & test.....

Thank you for your help on the compiler.:)
