With SIM 555 installed, it may not properly recognize a proxy configuration (regardless of proxy credentials).
In this case, The SIM can never 'connect' to our servers to obtain the proper information for our Product Listing, meaning all Products install items will appear grayed out.
Here is how it was noticed:
1. SIM 553 installed on a customer system
2. Customer updated the Product Listing and received SIM 555 upgrade
3. When SIM 555 launched, it could not 'see' Products install items. All showed as unavailable and grayed out with 'requires internet connection' message.
4. In some other cases SIM was not able to recognize the customer's Proxy settings so he was not able to obtain access to the Internet
Cause
Some changes in SIM 555 code caused some unexpected behaviours during our attempts to connect to the Internet
Resolution
This issue has been reported to our Development Team. A permanent fix has been developed. This issue is fixed with SIM 7.0.556 version. Please check for updates in SIM.
Note: If SIM is not warning you about installing a new version or it is not able to obtain it, please see the attached file. It should be SIM 7.0.556. Just unzip the file and run the executable to upgrade SIM.
