Hello dear friends ! One of my friends of Diaporamaforum lets you know by my intermediary of the following problem: He says : A few weeks ago I updated my pc-os from Vista to Win-7. All seemed well to go with the whole of the softs installed (Adobe coll CS4 inter alia ...) except for one of them : PTE. In fact PTE is completely blocked as soon as a new project is created, just after having added 2 slides for example. The PTE files already realized are read well, but impossible to modify them without causing blocking. I therefore unstalled PTE version 6.0.1, and then reinstalled it, I reinstalled the key, lounched Cleaner expecting to see some errors founded into the register, tested a former version ...... without any success. Since all went well with Vista before I would be tempted to show win-7 like culprit, but knowing that other users of PTE/Win7 do not have these dysfunctions, I cannot which solution to find myself I would like neither to remove Win7 nor with PTE of course. So I kindly request to you your help in the matter while hoping to find an issue Thank you very much in advance for your support. A desperate PTE forumeur !
