How to fix "solver. xlam is missing" in Excel 2007
Hello! So im a beginner in using excel. My lecture has told me that i have to install solver in order to finish my task in his class. So, when i click file > excel option > add ins > check the solver, it says "Microsoft Office Excel cant run this add-in, this feature is not currently installed. Would you like to install it now?" ANDDDD when i click yes, at first it start to installing, but in the end it says that "Microsoft Office Excel cant run this add-in, this feature is not available" :( And then it says "Microsoft office excel cannot access the file 'solver. xlam' blablabla"
What i supposed to do? I have seen many tutorial in youtube and read questions in this site but cant find the answer. I hope you can help me, thanks in advanced!
