An update to the Tech2win software (Version 2.336) was released on April 22 in TIS2Web. The software includes a fix for the MDI/MDI 2 Device Explorer not coming up for some users. The digital certificate was also updated. Users should update Tech2Win at their earliest convenience to avoid warnings of an expired certificate.

The Tech2Win update is available by clicking on the Software Download icon or the Utility Tab located in TIS2Web

In addition, an update to the GDS2 core software (Version 21.0.01501) was released on April 15 in TIS2Web. The GDS2 update includes numerous bug fixes.

The GDS2 software update is available by selecting the GDS2 icon in TIS2Web. 


Updating Software

When updating to a new core version, many firewalls/antivirus programs will recognize it as a new application. It may be necessary to engage your local IT support to ensure GDS2 is entered as an exception in these programs to allow normal functionality. GDS2 users also need full administrative rights to install the update. If issues are encountered with GDS2 not functioning properly, right click on the GDS2 icon on the desktop and select “Run as administrator.”
