Hi all, i have a WIZ125SR module and it worked very well with WIZVSP until yesterday when pc has been updated. I have 2 virtual ports created with this software and now i can’t open the communication in any of these and if i try to delete and create a new port, a message “cannot add the defined connection” appears. In the pc there is Windows 10 Pro x64 and i always run software as administrator. ## Replies ### Reply 1 by Egis K, 2018-07-29 ![](https://avatars.discourse-cdn.com/v4/letter/a/a183cd/48.png) andnuc: > Hi all, i have a WIZ125SR module and it worked very well with WIZVSP until yesterday when pc has been updated.

In the pc there is Windows 10 Pro x64 and i always run software as administrator. I have the same problem. Windows version : Microsoft Windows Pro x64 1803 [Version 10.0.17134.191] ### Reply 2 by andnuc, 2018-07-30 (in reply to reply 1) I solved the problem. In the download page of WIZVSP, in description, there is yet the “2017. 04. 28” version, but if you redo the download, there is the “2.0.2_R2” version that work correctly with last update of Windows. ### Reply 3 by Egis K, 2018-07-30 Thanks, redownloaded, and it seems work. --- Source: https://maker.wiznet.io/forum/12997
