In that case I am willing to try and give it a go. That being said In the thread I read it has a reference of a text from dll.xml file, which may help in fixing this problem. Are you saying there is something wrong ('faulty or missing') with my computer or there is something wrong ('faulty or missing') with the Aerosoft product I have just bought. The real problem is the fact that I am a Aerosoft customer who's only interest is in aviation and in flying aircraft and have no 'computer programming knowledge'. And I should do, what exactly? to fix this problem. I understand you said it is a faulty or missing XMLTools install. Also once I read it I still have no idea of what it is saying.
