You really have two issues in play, both conditions are covered as part of the installation requirements
- 64 bit operating system, 32 bit vugen. See release notes on recording 64 bit applications. Crossing the WOW32 divide usually does not end well for a 32 bit app trying to control a 64 bit one. Going the other way is typically cleaner.
- Version of Browser. Always check the version of the browser supported and never use an unsupported version. Doing so places you in a questionable supported mode in your testing environment which should be hardened from items which have unknown performance or quality.
