I can't start DE on my iMac with Lion.
I get the error that DE is an PowerPC-program.
How can I solve this problem?
ADE can't be installed on Lion. Either install it on a prior version of OSX (like in a swparate partion on your hard drive) or wait for Adobe to make ADE compatible with Lion (although who knows when that will be!).
In the mean time I had installed the betaversion from the Adobe Lab
