One option could be to use Domain accounts for WPM player and then use GPO to set IE compatibility mode settings - https://technet.microsoft.com/en-us/library/dn321457.aspx
Domain accounts can be configured using "c:\Program Files (x86)\SolarWinds\Orion\SEUM\Player\SolarWinds.SEUM.AgentDomainConfigurationTool.exe" where you enter account credentials and WPM player will run transactions using these. You need 7 different accounts for the player but you can use the same set of accounts on different players.
