M JayMar 7 2019 — edited Mar 22 2019

Hello Community,

i have downloaded SQL Developer 18.4.0 64Bit, unzipped it in C:\Program Files\sqldeveloper but it doesn't want to start.

The downloaded filename was sqldeveloper-18.4.0-376.1900-x64.zip.

About my system:
- Windows 10 Pro Version 1803
- Java 1.8 Update 201

- Two monitors

- 8 GB RAM

- 64-Bit

- Intel Core i5 (2,4 GHz)

What I have done so far

- installed the newest updated for Windows

- tried to run this Tool as admin

- tried to copy it to C:\sqldeveloper and started it from there, same reaction

The tool displays this and the process stops to continue.

Greetings from Germany
