the following type of error may be shown:

Error message: Cannot load DLL of any version for 'usdora'. Reason(s):

C:\Usd91\BIN64\usdora.dll

C:\Usd91\BIN64\usdora10.dll
C:\Usd91\BIN64\usdora90.dll; The specified module could not be found. >

The error is caused by the Oracle client that is missing or when the incorrect version of the Oracle client is used against USoft. For example, when a 64 bits USoft installation runs against a 32 bit oracle client or vice versa. It can also occur if the path towards an Oracle client is missing in the Windows environment variables. This error can also occur after a fresh install of Oracle after which the user does not reboot the system and runs USoft immediately after the install. Installing an Oracle instant client in the BIN64 / BIN directory of USoft is a workaround for solving the error until the cause is determined.
