Cannont install ContactMap under => J 3.4

Hello,

I have been running ContactMap 3.5 under Joomla 1.5.26 without any problems and want to use the same component for the migrated version of my website running under Joomla 3.4. But it is not possible to install the ZIP-File I downloaded from
gmapfp.org/en/download/func-startdown/45/lang,en-gb/

In Joomla 3.4 I selecting the ZIP-File "com_ContactMap_J3.19F.zip" and uploading it results in no result.
The browsed name of the ZIP-file is resetted, that´s all. The component is not installed. Same problem with installing it from a directory.

Afterwards I updated Joomla 3.4 -> 3.8 and tried again to install ContactMap.

I get following error message from the installer in the extension manager:

Warning
Unknown column 'name' in 'field list'

Error
Error installing component

COM_CONTACTMAP_XML_DESCRIPTION

Trying to install ContactMap from a folder prints out following errors:

Warning
JInstaller: :Install: Can't find Joomla XML setup file.
Error
Path does not have a valid package.
Unable to find install package

Can you please help me and give me a hint why it is not possible to install ContactMap in my case?

Thanks and best regards
Sidney

EDIT#1

Strange: I tried it with "Or browser for file" in Joomla 3.8 and now the installation was successfull. But the installation message is
"Welcome on vJ3.17F ContactMap !"
although I installed com_ContactMap_J3.19F.zip

Unfortunately - although having used a professional migration component (MigrateME) for migrating Joomla 1.5.26 => 3.X the defined contact and GoogleMap-Parameters etc. from Joomla 1.5.26 are not considered.

Thanks for your reply,

but could you please give me a hint concerning my question from above:

"Unfortunately - although having used a professional migration component (MigrateME) for migrating Joomla 1.5.26 => 3.X the defined contact and GoogleMap-Parameters etc. from Joomla 1.5.26 are not considered. "?
