Using Exponent on Windows NT


Windows NT has extra security features that can prevent access to files and folders on a per user basis. This can prevent Exponent from saving some user configuration parameters. One of the common indications that security permissions are a problem is an error message that states the Testlog can not be accessed or locked after a test is complete. You may also find that your Macro and Project manager settings are not accepted.

To ensure this does not inconvenience users then all the files and directories located in the TE32 "Application Data" directory specified by Windows need to have read/write privileges. This is normally something like "C:\Documents and Settings\All Users\Application Data\StableMicroSystems\TE32" but you can find out for sure in the About box of Exponent (Help > About menu command)

Exponent tries to create the permissions when it creates the folder but this may fail if the active users NT permissions are not sufficient. For this reason it is recommended that Exponent is run for the first time by a user with Administrator rights on NT.

Some global settings are stored in the HKEY_LOCAL_MACHINE\Software\Stable Micro Systems\TEE32 branch of the registry. If you need to allow users to change these global settings then the security settings of this branch will also need to be configured accordingly. Normally these settings are not changed very often so provided Exponent is initially configured by an NT administrator then the standard privileges should be OK for normal use. Exponent tries to create the permissions when it creates the registry entry but this may fail if the active users NT permissions are not sufficient. For this reason it is recommended that Exponent is run for the first time by a user with Administrator rights on NT.

The following items are stored in this branch of the registry:
