cant upload software

hi i am trying to reinstall my lightroom software which was running with no problems before, but now it says it cant verify the software as being genuine?
anyone had this problem?

ps the software is 100% genuine

Adobe Photoshop Lightroom 3 ? I personally don't have this product but are you saying Windows warns you it may not be genuine when you go to install it OR that the product gives the error?

If windows gives a warning on install it is likely the certificates are just out-of-date but if you know it's valid software you can just choose the Yes install anyway. If it is the product somehow saying it isn't genuine then I would contact the manufacturer's support.

its windows that give the error msg,there is no option for install anyway or now, how do i check the certificate?
thanks

could you take a screenshot of the error and post it?

you will need to use the "post reply" button and then the paperclip to attach (quick reply does not offer the attachment feature)

as i cant post the screen shot here is what it says:-

The installation package could not be opened
verify the package exists and that you can access it
or contact the vendor to verify this is a valid windows installer package

can anyone help?

What version of software is this? is it designed for Windows 7?

Create a folder C:\install
Copy the install program to that folder
Right-click on the install program and go to the compatibility tab
Check "run as administrator"
IF it is not windows 7 software also set compatibility to "XP, SP3"
apply and run
post results.

hi no luck, the message is the same there is an icon next to install that says" run as administrator"
ps i didnt see a compatibility tab?

an icon next to it? it sounds like you created another file and named it
run as administrator", You need to right-click on the installer executable and select properties. From there you should see the "compatibility" tab.

hi i created a new file like you said, that didnt work i tried to download the software and that didnt work either, is there an update or patch for windows installer?
