This is actually not an "error", but rather the expected behavior of the program. Whenever your system administrator installs a new version of MDsuite, all of the workstations need to be updated to the new version. Rather than install the new MDsuite workstation program on each computer manually, MDsuite automatically prompts each user to upgrade.
If you installed MDsuite in the default location, then you can simply click Next and allow the program to install. If you did not install MDsuite to the default location, then you will need to click Browse and select the appropriate installation path. (If you're not sure what to do, just click Next until you get to the end, and then click Finish.)
Here's how the situation usually goes:
Next and Finish, and the installer completes without any problems, and you get into MDsuite without any problems.The "problem" is that you have not installed MDsuite in the default location. So, in a nutshell, here's what's happening:
C:\Some\Other\Path\To\dsclient.exe
C:\Program Files\DSI\MDsuite Workstation\dsclient.exe
We have two options to solve this problem: either change your shortcuts to use the default path, or remember to install the new workstation program to the non-standard location that you've been using.
