This applies any Virtual Connect running firmware versions 3.30 to 4.01.

I had an issue recently when administering a Virtual Connect domain (through Virtual Connect Manager/VCM) running firmware 3.70 whereby upon logging in it stuck at loading libraries at 4% (see screenshot below), no matter what browser or device was used.

This will occur because the Virtual Connect Manager UI requires the use of Flash Player and the digitally signed files used by Adobe Flash Player expired back on the 5th May 2015. Fortunately this is easy fix.

Solution

Download the following 7 files directly from Adobe to a temporary location. Note these links are external to this blog.

Open a command prompt as an administrator and CD to the location of the downloaded files and use the following command to rename the files.

ren framework_4.1.0.16076.swz 871F12AF0853C06E4EB80A1CCAB295CEADBB817A.swz
ren framework_4.1.0.21490.swz F78F74378B1552FF9A1725155D1B43BA54BE9094.swz
ren osmf_flex.4.0.0.13495.swz C3306B26751D6A80EB1FCB651912469AE18819AB.swz
ren rpc_4.1.0.16076.swz 6DDB94AE3365798230849FA0F931AC132FE417D1.swz
ren spark_4.1.0.16076.swz 6344DCC80A9A6A3676DCEA0C92C8C45EFD2F3220.swz
ren sparkskins_4.1.0.16076.swz 440AE73B017A477382DEFF7C0DBE4896FED21079.swz
ren textLayout_1.1.0.604.swz 381814F6F5270FFBB27E244D6138BC023AF911D5.swz

Once renamed copy the files to the following locations (overwriting if needed).

Windows OS: %appdata%\Adobe\Flash Player\AssetCache\{directory}
Linux: /{user}/.adobe/Flash_Player/AssetCache/{directory}

Restart your browser of choice and it should now be working.
