3DCalc : BugReport
DiamCalc & GemCalc bugreport.

Dear Madam/Sir,

Please, read this information carefully. This letter contains the detailed information about an error in installation kits of our software dated by July 2002: DiamCalc 2.1 (build 216) and GemCalc 1.1 (build 216) available on our site from the July 28, 2002 till the August 18, 2002 and instructions how to eliminate influence of this error on the normal work of the operating system on your computer. If did not download ether of the files listed above or you have only Windows XP operating system installed on your computer, there is no need to read further.

For everyone who downloaded versions of DiamCalc or GemCalc software dated by July 2002 from our site we recommend to update the MSVCRT.DLL that should be in the WINDOWS/SYSTEM or WINNT/SYSTEM32 folder. It is better to take this DLL library from the distribution kit of your operating system. Please replace this DLL library as soon as possible and before the reboot of the system.

If your Windows fails to start then PLEASE DO NOT REINSTALL WINDOWS. There is no need to reinstall Windows, the only thing you need is to update one file.

If you can't get this file from distribution kit of your operating system, you may download it from the web-page of our site:

The MSVCRT.DLL for the Windows 98 and WinNT operating system. File version 6.00.8797.0. It should be placed into Windows/System folder on Windows 98 and WinNT/System32 on Windows NT.
The MSVCRT.DLL for the Windows 2000 operating system. File version 6.10.8924.0. It should be placed into WinNT/System32 folder.

If you don't know how to replace the file, please contact us and tell us the version of your operating system.
We would do our best to help you (even if your Windows does not start).

Here is the cause of the problem and possible consequences. The latest installation of our software accidentally included one system file from Windows XP. When you run the installation on the previous version of Windows it replaced this file (msvcrt.dll) with the new version. After that all applications that somehow used this system library refused to work. This reveals as the following error message when trying to load such a program: "The MSVCRT.DLL file is linked to missing export NTDLL.DLL: RtlGetNtVersionNumbers" If you have some programs that are loaded automatically at the system startup you may encounter such an error right after the system boot or system fails to start (this possible, for example, with some anti-virus software). YOU SHOULD NOT REINSTALL Windows even it doesn't start. You just need to update msvcrt.dll file. If the Windows doesn't start then you can update file through the command prompt or emergency repair disk.

The following Microsoft article describes that procedure for Window 98 and Me:
http://support.microsoft.com/default.aspx?scid=KB;EN-US;q299296
If you fail to replace the file or don't know how to, then please contact us

Please don't hesitate to contact us if you encountered any problems. We deeply regret that we didn't prevent such a vexatious error that may give you a lot of trouble and lead to the waste of time.

In the latest software release we've changed the software architecture to preclude a possibility of such problems in future.

We apologize that we informed you of this error with such a delay.
Please, contact us if you encountered this error.
