Preparing Biochrom Software for use with multi level users on Windows 2000 and Windows XP Pro. How do I set Biochrom Software to work in different User Accounts?


Biochrom software uses the Registry to store both its User and System settings. User settings are stored under HKEY_CURRENT_USER and System settings are stored under HKEY_LOCAL_MACHINE. However, on secure systems, such as Windows 2000, access to HKEY_LOCAL_MACHINE is restricted, normally to administrators only. This can cause some Biochrom software to behave in an unpredictable fashion.

If it is required that the users on a system have restricted access, i.e. they are only allocated User or Power User access, then it is possible to enable the specific areas of the Registry for the users.

The following procedures will allow the Biochrom nodes of the Registry to be enabled.

With Administrator privileges, run the program REGEDT32.EXE. This is normally found in the WinNT\System32 directory. Select the window titled HKEY_LOCAL_MACHINE and browse to the Biochrom directory. Select the software to be enabled and then select the Security>Permissions item from the main menu.

If specific users are to be given access to the software, then add their user names to the list of names, otherwise select the user level to be given access, i.e. Power User, User etc. For each user or group of users, ensure that both options Read and Full Control are enabled. Select OK, to accept the changes and close the REGEDT32 program and the selected users should now have the required access rights to run the Biochrom software.

At present, the current list of software, which may require this fix, is: Acquire, Acquire Lite, BioSys, SWIFT II and SWIFT II Lite. This list may be expanded with the development of new software.
