Hi guy's! Have you tried to copy the navtweak.exe to the C:\GTK\bin directory and run the application from there? I think that will do the trick...
Let me know if it works!

I was having problems installing Gtk+ and Navtweak on Vista 64... this is what I did: first download Gtk+ and install that. Only then download Navtweak, then it worked with no errors.

Also, I couldnt even install Gtk+ at first on Vista, it kept throwing out incompatibility errors.. so I downloaded the RAR file on my older XP, then copied over the extracted .EXE file via USB stick over to Vista and then it installed.

If you have problems with running NavTweak even after the installation of GTK try to reinstall GTK one more time - I hade several times the same problem (on XP and Vista as well), in all cases I succeed to run NavTweak after additional installation of GTK

And try to use the latest version of GTK - I use gtk2-runtime-2.14.7-2009-01-13-ash.exe

First of all - 2009.1 is not a software it's a version of map.

Regarding your question - are you sure that you've download High version for MK4 and not Professional for CCC?

Well, I'm stumped. I've been struggling to upload modded software but I keep striking out. I've read through this entire thread and I think I've tried everything.

I'm running a Mark IV Nav with V32 software. I've modded the V32 Navboot splash screen, car icons, and warning screen text using Navtweak. I've also changed the 4th bit in sw_rel.tbl using pspad to force the upload of the modded software. I've replaced these files in the iso using UltraIso. I've burned the new Iso image to a CD-rom with no problems.

When I insert the disc into the computer, things progress normally, I get the message that software will be updated, the progress bar fills all the way up ....then I get a screen that says something about "errors encountered, please see user manual, eject disk and click ok". The nav goes to a black screen, until put the regular V32 disk in. The regular V32 disk installs normally and then system works fine.

Any thoughts on what I could be doing wrong when I create the modified V32 iso?

I'm comfortable with the navtweak changes but not terribly comfortable using the hex editor. Does anyone have a working link to a copy of V27, so I can load an old version and then install a modded V32 without having to adjust the software version using the hex editor (none of the links in the forum seem to work anymore).

you were correct. thanks
