Someone is running an old app written in Delphi 6 using DBISAM 4.2x on their nice new W7 64bit machine and are getting the following error:

---------------------------
Techniques.exe - No Disk
---------------------------
There is no disk in the drive. Please insert a disk into drive \Device\Harddisk1\DR1.
---------------------------
Cancel   Try Again   Continue
---------------------------


All they've done is copy from C: on the old PC to c: on the new one. It doesn't use registry keys and should just run. Any suggestions?

I suppose it's not your app, otherwise you would know. In any case it may have nothing to do with DBISAM. If it's someone else's app, hell knows what the problem is. I worked for a company that copy protects their apps, so what you described would have the same consequences there (copy won't work, registry not used). They will crash however with a different error message because they at least call SetErrorMode(SEM_FAILCRITICALERRORS)...

Sorry if this wasn't helpfull ;-(

It is my app

Unfortunately I don't have a high spec W7 64bit machine to play with and living something like 800 miles apart we're unlikely to physically get together on the issue.

My current thoughts are 1) its the AV - dear old Norton or the PC is just to fast for the software.

Well, Roy, I do have a W7 64-bit laptop and I am less than 200 miles
away, so if it is possible to zip it up and put it somewhere I could
grab it from, I could give it a quick whirl to see if I get the same
error.

But it sounds as if there is some reference to a device/path that
does not exist on the new machine.  No ini file, database path, etc?

If you want to do it privately, try malcolm at mdt dot co dot uk

That's very kind of you. I'll email you the stuff.

I'm trying to email at the address you've given but its bouncing back. It would be c4Mb - could that be a problem?

No problem.
Got to pop out (foot and bus as car is froxen solid) to put up
sister's 'tree' and lights, so I will be away for a few hours.  Hmm,
I wonder if I will be paid in mince pies - yummy.

Yesterday I had to climb into my car via the passenger door since the driver's door wouldn't open - might have had something to do with the 18 or so inches of snow I had to remove to even see the car

Hi Roy,

<<But it sounds as if there is some reference to a device/path that

My thoughts too.

I haven't had any reports from my customers about this but if you still have
the source, you may have overlooked the following :

- That the session, database and datasets are all closed at design time so
the app is is not accessing any design time path on the target machine when
the app starts
- That the Session.PrivateDir is set to a valid path at runtime and its not
using a non existent design time path.

Could also ask the user to :
- Confirm that the hard disk is configured as C drive and that C does not
point to a removable disk.
- Update their copy of Windows as it could be Windows/ hardware issue.

Got to go now. My daughter's preparing Christmas lunch. Merry Christmas to
all.
