Hi

I tried to install the demo:  I have win 7 32 bit and Lightroom 4.0  OK that's all a bit old but works for me.

I downloaded and installed the demo.  The path to the LR presets seemed correct.

I get this error message:

An error occurred when starting the application

The version of %1 is not compatible with the version of windows you are using.  check whether you are using a 32 bit or 63 bit version of windows then contact the publisher.

regards

Julian

In the start menu you will find an alternative launcher for 32bit systems.

Thanks!

Regrettably it still doesn't work. I tried "Run as adminstrator" and also windows compatibility settings but it won't launch. I'm clicking on win 32 in the start menu.

Do you have java installed?

Thanks. I'm not a techie person: it says Java 8 version 25. I'm sure this means something to someone....:-)

I'd suggest you uninstall everything related to java via control panel and then download and install the latest from here:

Choose Windows (x86) offline
Then try again.

Well, well, well.  There's no accounting for the irrationality of computers!

After removing all Java and reinstalling the latest version,  I couldn't get LRT4 to launch.  I did get the additional bonus of ADChoices Malware, which presumably was lurking somewhere and couldn't use my old version of Java. (sigh)

After several attempts, I tried to install LRT4 on the same drive as LIghtroom (which is not on my C drive, for a variety of reasons).

It didn't install there - but it does work!  Maybe it was that extra cup of coffee I had this morning :-)
