OK, FileMaker lets you downlaod an installer in the DMG format (disk image file).
Quit ingenious, just double-click and the file installs itself as any other harddisk.
But, unlike with most other installers, FileMaker does not allow you to install from this disk directly.
It does not tell you this, it just lets you get along, fill in the licence key and then halts claiming there is already/still an older version of FileMaker installed.
Copying the content of this virtual disk to your desktop magicaly resolves this problem and all is well ... sort of.
Having installed many times from the FMP/A/S Mounted Disk Image (.dmg) I can say with some confidence that this is possible.
Could it be you have Virus Protection software that is preventing the install from Disk?
Thanks for replying.
I'm not sure but I don't think so.
It's a cients server, so we don't have constant access.
But I made a note in our logbook... It won't happen again!
