Mathcad stopped working on Windows 7 computer

[resonator80]

I have a Dell Inspiron 1440 computer running Windows 7 Home Premium, 64 bit.

I have Mathcad 14. It has been running fine for well over a year on this machine.

In the past few weeks, however, Mathcad refuses to start. I click on the Mathcad icon and the hourglass appears. Then after a while the hourglass disappears and there is no Mathcad window.

I reinstalled Mathcad 14 and it still doesn't work.

Any advice?

Thanks,

Hello!

Try to restore your Win7.

P.S. Do you have an active (paid) maintenance for Mathcad?

[resonator80]

Hi Vladimir,

Win7 refuses to restore, says there is some error when I try it. There are more "advanced" restoration alternatives that I can try (if I understand them).

No, I do not have Mathcad maintenance.

Thanks for your suggestions.

What version of M14 are you running?

Mike

[resonator80]

Mike,

The disc says Mathcad 14.0, Datecode M020.

I don't seem to be able to find out any more since I can't get Mathcad to open.

Thanks,

Weird. Does that happen when you open by clicking by file?

Hi Bill,

Did anything else change on your computer, such as a Windows update? Make sure you installed Mathcad 14 as an administrator. I know there's been issues with Mathcad 14 on Win 7 in the past. It usually meant that you had to be an adminstrator on the machine.

Try right-clicking on mathcad.exe in the Mathcad 14 installed directory, and choose Run as an Administrator.

Hi Mona,

I have tried running as an Administrator, no good.

I just tried uninstalling and reinstalling as the Administrator user. It says everything worked. But when I try to run Mathcad in the Administrator user, it says

When I go back to my usual userid it tries to run and never opens a window, just as before.

Help!

Mike,

When I click on a previously saved Mathcad file, an error message appears that says "There was a problem sending the command to the program" and nothing happens.

All I can suggest is trying to restore your computer to a point where Mathcad was working.

Mike

[resonator80]

Unfortunately, the computer refuses to restore, and the earliest restore point I see is only about a month ago.

Isn't Windows wonderful?

Bill

[MikeArmstrong]

Frustrating to say the least.

Has your Mathcad been broken for over a month?

Mike

[resonator80]

I believe it has been broken for over a month.

When I tried to use Mathcad and failed, I just got out a calculator and did other things. I finally decided that I was going to fix it, but I couldn't. So that's where I am now.

What is the error you are arises when trying to restore the system? If you have a disc (CD/DVD) with Windows 7 (which should be when buying a computer), then there is the option to restore the system, it seems it is called "Update".

Vladimir,

Here is the message when I try to restore. I have tried turning off my virus prog (BitDefender) with the same result.

I have not tried the disc. Will that mess up all the Microsoft updates?

Thanks,

Please, see the answer at a forum "Microsoft Answers" from technical support MS, here: http://bit.ly/pOgo4a

If you boot from your Windows 7 disc and go to repair instead of install you will get the option to restore back to a restore point like you do in Windows.

Vladimir,

I tried the original W7 disk that came with the computer and it doesn't let me do "repair." It wants me to choose "upgrade," but that won't work either because my present W7 version is newer than what is on the disk. The internet says I have to get an independent W7 disk to do repair. So I give up on this for the moment.

Thanks for your suggestions.

Bill,

Try disabling the antivirus, then restart your computer in "Safe mode" and restore your system (using one of the points for the restoration, which creates Windows).
