Hello Nexus forums, I was recently struggling with some strange bug that made my character block all the time, whenever I drew my weapon. It didn't stop and I couldn't sheathe it again. At first I thought Deadly Reflex v5 was causing that, but apparently it wasn't. I was searching for the evil scheme behind this, but finally I gave up and deinstalled Oblivion completely, deleting every single mod as well. Now, thinking I might come to be happy with my new fresh, clean install, I am facing a new mysterious error. Whenever I start Oblivion (both Standard Launcher or OBSE) I get a CTD after the Bethesda intro, facing an InstallShield error message: "Install error! Nikon Movie Editor failed to install." or something like that. I tried reinstalling everything again, but not to avail. I hope someone around here has a helpful idea. Thank you in advance.
