I work at a school and have Math faculty requesting this. It would be nice if there were a silent install option (or if there is one, it could be documented!), so that we could deploy this to all of our lab computers.

For the time being, I'm deploying it via system center, but the users will have to click through the install themselves.

Thanks!

Within the automatic update detection form
When the user clicks on "Update Now" they may see a message like one of these :-

• "This program is blocked by group policy. For more information, contact your system administrator."
• "Access is denied"

This is happening because the user's anti virus system is detecting our auto update mechanism as an intrusion and blocking it.

Unfortunately we can't do anything about this, you will need to contact your system administrator.

We have determined that with certain structures the following exception can occur.

Describe the bug
In summary, I do not know why the registry keys are not being re-added to the registry when i try use the repair feature in the setup, but for this reason i cannot reinstall the Chem4Word plugin

To Reproduce
Steps to reproduce the behavior:

1. Go to downloaded setup.exe file for Chem4Word
2. Run Setup
3. Click 'Repair'
4. Load Word, and the chemistry tab doesn't appear anymore

Expected behavior
the chemistry tab should appear and the addin should work as expected

Screenshots
If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• Windows 10
• Word 2016

Additional context

• I deleted Chem4Word manually by deleting files and registry edits as specified by the Chem4Word Website
• I tried to reinstall, but registry keys were not reinstalled
• As a result, Chem4Word plugin did not load in/work

UPDATE: I (somewhat) fixed it by downloading Chem4Word on a different PC, then extracting and importing the registry keys into my PC's registry, which allowed the plugin to work. However, when I notice now that if I try to remove then repair the files, the registry keys are deleted then never reinstalled, meaning that I would have to manually re-add the registry keys. Is there a more permanent solution?

Hello, a couple days ago I deleted the chem4word manually using the steps on the website (because I didnt know it could do so automatically). Now i'm trying to reinstall it, but it won't work. When I checked through the files, they had downloaded into their folders, except for the folder located in 'AppData>Local', which did not contain the Chem4WordV3 folder after the reinstall. Also, the registry edits weren't reinstalled. What do I do in this situation? I tried running the setup over and over again and it did nothing (in hindsight I should have backed up my registry)

When I click on draw molecule, a script error appears.
  What should I do?

This error is caused by an missing file (which is part of the .Net Framework) on your computer.

It most likely happened durung the un-installation of another program, which has incorrecltly removed the file.

Microsoft have a tool which should be able to repair your installed version of the .Net Framework.

This can be downloaded from https://www.microsoft.com/en-gb/download/confirmation.aspx?id=30135

The form which allows a user to edit a structure uses an ActiveX control to start an embedded version of Internet Explorer (IE).

If Internet Explorer is not registered properly the exception shown below can occur.

As this is an issue which is external to Chem4Word, we are unable to fix this.

Greetings

I Installed C4W and received no install errors. However, when word is launched the menu is entirely grayed out with the exception of the Options & Help buttons. De-activating and re-activating the add-in has no effect. I uninstalled and reinstalled also with no effect. I rebooted the machine with no effect. Attached is the install log

2018-02-15.log

I also installed C4W on a duplicate set of hardware with no difficulties.

The machines in question are both Dell T7500, Dual Xeon, 12Gb Ram running Win7-Pro-64.

Thoughts on what to do?

Sincerely Paul

Although reported as an exception, this is caused by data which is not understood by Chem4Word version 3

Describe the bug
The plugin calculates an incorrect formula for caffeine.

To Reproduce
Steps to reproduce the behaviour:

1. Go to Chemistry tab
2. Click on Draw
3. Draw caffeine molecule
4. Click on Edit Labels
   Expected behavior
   Chem4Word: ResolvedFormula should read C8H10N4O2
   Screenshots

Desktop (please complete the following information):

• OS: Windows 10 enterpise
• Word Version 2019 Professional

Additional context
Add any other context about the problem here.

A disable auto-update option should be made available.
I have searched trough the registry and the Chem4Word.V3.json settings file but no such option is available,
This proves to be quite an issue as some people prefer to update to each version manually and the pop-up that shows at each run tends to get in the way for those people.

Thanks for the time and understanding!

Hi, I want to convert structures to SMILES format and show in Word. The problem was when I imported sdf structures from the Import icon, the 2D structures could not be shown as SMILES at the same time when I clicked the Show As icon. It seemed the imported structures were deposited in the same object. Any advices would be helpful, thank you !
