Hi Chris,
I have updated the Imdisk_Installer.script with the brand new stable version 1.7.4 built 13 June 2013 of imdiskinst.exe.
Everything works fine.
I have tested: RamDisk, ISO-mount/unmount, the controlpanel applet and the contextmenu commands (from ImdiskRamdisk.script).
Imdisk_Installer.script is now v.23
