To solve this problem you can use a license file. If a license file is found, ViewCompanion will not ask for a serial number. You can create this license file yourself. The file must be named viewcompanion.lic and have to be placed in the same directory as the viewcompanion.exe executable. The file must be a text only file (e.g. created by Notepad), and must contain only two lines. The first line holds the owner or company name, and the second line holds the serial number you've received from us.
Example license file contents:

Yes, we do permit a single authorized end user to make a second copy for end user's exclusive use on a portable computer as long as only one (1) copy of the purchased software is in use at any one (1) time. No other users may use the software under the same license at the same time for any other purpose.

If you have either Microsoft ® Office or LibreOffice installed on your system, you can convert Word, RTF, PowerPoint and Excel to PDF with ViewCompanion Pro and Premium.
You may convert both individual files and a batch of files and folders.
If you have LibreOffice installed you can convert additional formats like Visio (VSD/VSDX), SVG and WordPerfect to PDF. Check out the list of supported Office File Formats.

ViewCompanion support many markup tools including stamps, text, images, barcodes, symbols, revision clouds, lines, polygons, sticky notes and more. Each Markup entity maintains author and date information. Markup are stored in a separate file and the original document is not changed. Markups and original document can be combined into a single rendition and saved as PDF, DWF, TIFF or any other of the supported output formats.

Open the Markup->Settings dialog. On the General settings page you will find an option named "Switch to Edit Mode when a new entity is created". Disable this option and ViewCompanion will stay in the draw markup mode.

By default yes, but you can place markups on a locked markup layer to make sure only selected users can modify these. To be able to modify markups on a locked layer, a user would have to enter a password to unlock it. You can easily create a new locked layer by using the Markup Layer->Add New Layer dialog box.

On the Tools->Options->Formats->HPGL page you find a setting named "Use Pen Table for Text". Enable this option and the pen table settings will work for text (LB) entities too.

Under the Tools category you will find a button named "Application Theme", click this button to open the theme dialog. At the bottom of this dialog you will find a radio button labeled "Use Toolbar & Menu Based Interface", select it and close the dialog.
Restart the application and you will now be able to use the classic toolbars and menus.

The installation program supports the following parameters:

/SP-
Disables the "This will install... Do you wish to continue?"" prompt at the beginning of Setup.

/SILENT
Instructs Setup to be silent. When Setup is silent the wizard and the background window are not displayed but the installation progress window is. Everything else is normal so for example error messages during installation are displayed and the startup prompt is (if you haven't disabled it with the '/SP-' command line option explained above).

/VERYSILENT
Instructs Setup to be very silent. When a setup is very silent the wizard, background window and the installation progress window is not displayed. Everything else is normal so for example error messages during installation are displayed and the startup prompt is (if you haven't disabled it with the '/SP-' command line option explained above).
