I just built a new pc, x64, IE7. I'm having this problem with Adobe Reader:
Windows XP 64-bit and Internet Explorer 64-bit: will not open PDF documents from Internet Explorer 64-bit version. Both the 64-Bit and the 32-Bit versions of Internet Explorer can be installed under Windows XP 64-bit operating system. Adobe Reader 7.0 can, however, open PDF files in Internet Explorer 32-bit only. Acrobat and Adobe Reader install a 32-bit ActiveX controller (pdf.ocx), which permits the opening of PDF files from Internet Explorer. However, the 64-bit version of Internet Explorer 6 does not support 32-bit ActiveX controllers
Will there be any negative impacts on the my pc if I installed IE6 X32 and kept IE7 X64 as well?
If so, what setting do I choose to use IE7 but just to have IE6 available?
