Access Violation while loading files into IC8

[LordPython]

I an not new to backing up DVDs. And I have used InstantCopy for years, but lately when I load a file (any file) into IC I get "Access Violation at address 0000000. Read of Address 00000000." And it will not let me continue. I have found a work-around with this; if I simply click the Start button without selecting a file, it will ask me for my source file, and from then on work perfectly. Does anyone know why this is happening?

You probably have a file that it is referencing that is missing or in the wrong place, corrupted or misnamed. I would try re-installing the software.

And this isn't advanced conversion. Moving you.

Hello there!

I have the same problem. Long user of IC, it always worked fine, but now this problem has appeared: `Access violation at address 00425B90 in module MultiCopy.exe. Read of address 00000000.`
What`s more, I get the same warning on my two CPU`s (WinXP Pro SP2). The program simply stopped working normally as it used to, some time ago.
I tried yr workaround, but I had no success.
Can you help me this time, pls
tks a lot!

There's not much more I can tell you, not being familiar with the program. I suspect another program may be using that address and IC either can't access the memory location or the data there is not what the program expected. About the only advice I can give is to go to the website of the program and see if they have a FAQ page, or a forum, where you might get a specific answer.

If you added a program or a update to your computer and IC then started showing that error, then you might be able to remove the program or update and get everything working again.

Access violations addressing 00000000 are nearly always because the program doesn't check for the existence of something before using it.

For example, a program may be designed to open a file. To do so, it asks the operating system to open the file and return a "handle" to it. This "handle" is simply a number that the program can use that uniquely refers to the file. If there is a problem opening the file, the operating system will usually return zero - this has a special meaning. If the handle is zero (or "null"), then the program shouldn't use it. If it does, you get the access violation because the operating system and the CPU are designed to say "hey, wait a minute - you can't do that!".

The same thing can apply to a whole host of things - files, registry keys, bitmaps, text fonts and, very often, DLLs that the program loads. e.g., if MultiCopy.exe relies on a DLL called foo.dll, at some point, it will ask the operating system to load foo.dll into memory. The OS will return a "handle" to it so that the program can access the functions of the DLL. If the programmer (incorrectly) assumes that foo.dll will always exist, s/he probably (incorrectly) won't bother checking to see if foo.dll really does exist. As soon as the program tries to do something with the (non-existent) foo.dll, you'll get an access violation trying to access 00000000.

Given that you know the address that causes the problem, you should contact the author of InstantCopy to find out how to fix the problem.

Hello there!

I've had the same problems with InstantCopy (a great program, nevertheless). And I discovered the following:
1- It seems that this software has been discontinued (no more updates to Pinnacle's Instant CD/DVD, ex-InstantCopy);
2- The crashes (particularly "Access violation" or "Out of bounds IFO's") are due to incompatible files resulting from DVD ripping (by DVD decrypter); In this case, DVDShrink might help, because it's less demanding than IC;
3- If you try to use IC to work directly from the original DVD disc (instead of using ripped files), you might succeed, if the DVD is not encrypted.
So, I conclude that the crashes are not due to incompatibility with other programs accessing the same memory address, but only with some incompatible ripped files.

PS: Don't forget to use the program "RIPIT4ME" which works with both DVD Decrypter" and DVDShrink and intends to be an update to DVD Decrypter.
