Sorry for being such a bother guys... hmm... i run my custom WinPE, starts it, copies the local i386 to HDD, copies the iFLY and cfg files (right folder structures) and the runtimes off VB6 to the local hard drive after have had run a diskpart script.... the script the tries to execute the iFLY appz but faults with an error off: __________________________________________________________________ No hard disk drive Sorry, but it appears that you don't have a HDD(hard Disk Drive) in your pc. A HDD is needed to store the temporary files for the program, without one the program cannot run. The program will now exit. __________________________________________________________________ Also tried starting the app local to the CD and / HDD after verifying that files off the runtime and cfg files are in place.... I know that i am having a HDD in place... Any ideas?? ohh.. and i have verifyied that the files are all -R with attrib as they r copied from CD.
