Help needed badly

Guys I probably have downloaded around 10 Microsoft offices on this forum. but every time I install it, it just extracts then nothing happens or sometimes it always says an error on 2007 office. I finally got one that is working and I finished my powerpoint presentation for my finals but every time I save it crashes.
Someone told me to clean my registry. I did that and I also checked viruses. Please please someone help me on this. I have to do a presentation and I really need powerpoint badly
Answer #1
If all else fails use openoffice. You can save it as a powerpoint compatible file on there.
Sorry not sure why its crashing when you save though.
Answer #2
try PowerPoint 2003 just for the sake of schedule. After the presentation is finished and when u got more time u can check whats wrong with Office 2007 with more time
Answer #3
Ya I agree, start with office 2003 just to meet your deadline and work on getting 2007 later, either that or if you have another computer, use that one.
Answer #4
I actually have office 2003 too. about 3 of them. every time I run the installer it extracts then it says preparing to install.. but noting happens after that. =[ ..
I’m gonna try the openoffice that suggested.
I’m also using revo uninstaller right now.
Thanks for the help guys.
I still need more help if anyone knows what to do.
Answer #5
Someone told me to clean my registry. I did that and I also checked viruses.

What registry programs you used? And what registry keys you removed? Even TuneUp Utilities can mess up your computer if you do the 1 click maintenance i tried that and it ruined my virtual machine. If you dont pay attention to what registry keys you delete you might of screwed up whole OS.
Possibility one of the cracks you installed was bad. I suggest using Your Uninstaller 2008 to remove it and try again to install it. Have you tried the portable versions?
Answer #6
I used ~ Rogue Software BANNED ~. But just now I used revo uninstaller and it deleted thousands of registry inside Microsoft office folders.
There’s no cracks. It’s just CD-Key.

Thanks to all that helped me here. I really appreciate it guys.
